Here is one of a few of mine:

Capitalism: Starving Dogs of Submission

World domination game involving menu driven decisions and micro-management

Your goal is to maintain a strong economy and keep the rich richer to help fund electromagnetic transmission towers around the globe in order to get a better leash on the masses through mind control.

Basic mechanics are keeping the nameless faceless many submissive through desperation by artificially limiting resources.

Some missions include

Posting spies on retailers underselling goods at fair prices with aim of discovering legal loopholes in which to vilify and sue in order to shut the retailers down.

Enlisting artists and authors to herd masses into churches through ambiguous and underground philosophical suggestions hidden in movies and music.
Once in church the masses are much easier to persuade and influence their political decisions in tune with yours.

Funding political campaigns and propaganda to dismantle charity and empathy thus replacing with disdain for the unemployed and unfortunate in hopes to impede tax-funded benefit systems.

Ultimate goal is to accrue enough excess to mask five mind control towers in pyramids around the globe in a pentagonal, networked, web.

Moose Buster (I had never thought about a name for it, and this one's the first that came to mind)

A 2D platformer.

You play as Karl Kung, a Swedish politician who isn't a part of any party but got 100% of the votes in the elections, so he was given the title of Special Politician whose job is to be awesome, and the elections were held again to pick the normal politicians. Anyway, due to a bureaucratic error, Canada invades Sweden with their massive special Sweden Invasion forces and the country's parliament. The Swedish parliament hastily passes a bill that dictates that Karl Kung is to deal with the special Sweden Invasion forces so as to save the army's budget just moments before they (the Swedish parliament) get locked into a brutal rap and breakdancing battle with the Canadian parliament.

The gameplay would use innovative "I like Mega Man X/Zero/ZX a lot, I think I'll copy theirs" techniques.

Battlefleet: Gothic

Space-combat sim set in the Warhammer: 40,000 universe

the sims: real life

your car breaks down every now and then, you earn less than anyone you know, you never get out of town yet watch tv shows about people having fun in various beautiful locations, depression and drug abuse galore and then you commit suicide when the bank takes your one tiny room hut because you can't pay bills. It will retail for 49.99$ since it's standalone product :D

A Daggerfall/Saints Row mashup taking place in a cyberpunk/Tron-style vision of Canada, where you are an anti-hero who cruises around wrecking everyone's shit.

A man can always dream.

Am still waiting for an Eight-Legged Freaks FPS adaptation.

A open world DBZ RPG that doesn't change to a fighting game for combat and follows all sagas

I started a thread on another forum where I post random game ideas. Here are a few of the ideas I've already come up with:

Military Mentality
FPS where two military units are engaged in battle. Your character dies or is immobilized in one shot. If you are killed, you suddenly control a new character in the battle. Each new character has a different running internal dialogue with different worries/motivation/etc.. You fight until one unit has either had every soldier killed or they surrender.

Phantom of Peace
A game where you are a ghost that must haunt political offices to prevent the country from going to war. You can't talk or be seen, but you can move objects when nobody is looking.

Gato del Asesinato
You are a supposedly "domesticated" house cat, but you have to unleash your animal urges to kill mice and birds. This must be done in secret, for if your owners find out about your murderous impulses, they will surely kick you out on the street. You must manipulate them to think you are a sweet kitty, but go too long without a good kill and you become moody and involuntarily scratch the hell out of the nearest human (which, obviously, also gets you kicked out). Meanwhile, the mice and birds have plans of their own to blow your cover...

Chat Bot Murder Mystery Theatre
PC murder mystery detective game where you have to interview local townsfolk to find the killer. All the NPCs in the game are chat-bots, but each holds a unique piece of information necessary for solving the mystery. You don't know exactly how to get the information you need from them, so you have to carry on conversations until you strike gold. You must collect enough evidence to be able to land the killer in jail.

Vampire Mom
You are a mother whose toddler is a vampire. You have to exist in polite society, yet still find a way to let your baby feed without getting a lynch mob after your boy. Will you lose track of him when you take his older brother to soccer practice or while you're distracted in the grocery store? And just what are you supposed to do with all the bodies when the girls come over for bridge club?

Mr. Hopeless!
A game of nay-saying! You're depressed. People in the game give you advice on how to improve your life. Your goal is to find a way to misuse/abuse their advice to lead to your own self-destruction so you can prove to them just how very wrong they are. You win if you make your own life so horrible that it is a puzzle nobody else can help you solve. You lose if in trying to prove them wrong, you accidentally use their advice in a way that actually works.

From The Heavens Above
Gods and angels have returned to the planet Earth... or have they? Conspiracy theorists claim that the returned Gods are not our benevolent (and vengeful) creators that have returned, but rather an alien race that has studied our mythologies from afar and are now using our most sacred beliefs to manipulate humans to willingly surrender their planet and turn against each other. Where will you side in this epic battle? Do you have faith in the Gods and plan to help shepard in a new era, or will you rise up against what might be alien overlords? What if you're wrong?

(This will basically have two games. When you start a new game, it randomly decides if the returned Gods are actually gods or impostor space aliens. You will either be a hero or villain based on your assumptions.)

Culture Shock
Games can take us to bizarre worlds, but I don't feel like anything really takes us to a bizarre culture. In Culture Shock, a science experiment gone wrong leads you through a dimensional portal that drops you into an alternate version of humanity with no way of returning, so you are forced to fit in. People greet one another by licking each others faces. Displaying your children in public is shameful. It is bad manners to stare towards the doors in an elevator. Stylized eyebrows are in fashion. If you go 5 miles under the speed limit for over 5 seconds, other drivers have the right to push you off the road. Having more than $100,000 dollars is punishable by death. You figure out the rules of this society by observation and trial and error, but if you make too many mistakes you may be ostracized, businesses will refuse you service, and you might even end up in jail or killed. The objective is to make friends, keep a job, and develop your polygamist family so that you can live happily ever after in this brave new world without anyone figuring out you are from another dimension (which is, of course, illegal).

Monster Trainer
A game where you use the principles of operant conditioning and clicker training to capture monsters in the wild, train them back at your ranch, and then use their unique abilities to find more monsters and ultimately collect enough to take over Manhattan. You have to train new abilities to solve specific puzzles.

A realistic terrorist simulator. One where you can choose to found a terrorist group, and then commit attacks and stuff, with the final objective up to you(world domination, anarchy, theocracy, depending on what ideology you choose).

I remember playing that on DS. Fantastic game.

My game is basically Far Cry 3, but with more realism and no RPG elements.

A horror adventure game about a girl called Rose who has been diagnosed with schi... ^^

(not mine exactly, but may I say, ours? too bad real life crap is a priority right now)

I don't have a DS. What DS game is like that?
Are you talking about Rule of Rose?

Not at all. :p First time hearing about such game.
