ARCANUM. Sure it's flawed, but it's still fantastic. I've also been alternating between the Humble Bundle games.

I'm a bit curious to play that. I bought it recently but I didn't plan to play it now but I do lack installed single player games.

In what way is it flawed and what makes it fantastic? :)

The main flaw is that it's a bit unbalanced due to it apparently being rushed out the doors too early (as with every Troika game, sadly). Firearms are very weak early on, there's one really annoying early game dungeon, and there are some other annoyances, though nothing near a deal breaker for me. Also, the intelligence of the party AI is somewhere between goldfish and rock. That being said, everything else about it is pretty great. The character creation/development system is my favorite in any game ever, you can play almost any build you can think of and then some (Escaped mental patient gnome grenadier? Idiot savant Orc mage? Frankenstein monster Elf warrior?), the world is big and open with a lot of choice, the story is interesting and the writing is good, I actually like the combat for the most part (I seem to be in the minority for this), and the world and lore is unique and cool. I like pretty much all of the companions as well, which is nice. I've seen complaints that a lot of them don't have story arcs, but I actually find this refreshing, feels more like you're recruiting actual random people who happen to want to adventure as opposed to big epic hero-types all the time. If you liked Fallout you'll probably like Arcanum as it's similar in some ways, and if you didn't like Fallout you might still like it (I found it much more compelling than Fallout, personally). TL,DR: Play it now. It's flawed but it's still one of the best cRPGs (my personal favorite).

Having another look at Babylon 5: I've Found Her, Where In Time Is Carmen Sandiego, Doom 3 and Half-Life 2 occasionally. Painkiller: BooH for the first time.

Overall progress is quite slow, though. Too much else to do.

I have a few games in various states of completion. But.. these are the ones I'm actively working on finishing.

Dark Souls (Beat the game a few times already, just trying to get all the rare weapons for 100% completion)
Baldur's Gate 2: ToB (It's my yearly playthrough)
Broken Sword
Wing Commander 4.

Guild Wars mostly, but also Sacred Gold.

Mostly Baldur's Gate - Shadows of Amn - 5 separate campaigns going. 1 is almost finished.

Also played the first few maps of Company of Heroes recently, will continue when I'm in the mood for strategy again.

I started a campaign of Third Age Total War last month as well (a Medieval II Total War mod for playing in Middle Earth), but the last 3 years I'm more into RPG's.

I forgot one very good game as well: Fallout 3. I'm looking forward to playing Fallout 1 and 2 and above-mentioned Arcanum if I have finished some of my BG2 campaigns.

I really like not having to worry about building when doing combat too much. Thus far Company of Heroes gives me less sensual-stimuli-overload than Age of Empires or Rise of Nations.

Have fun. I hope you like it. You might need to give yourself some time to get acquinted with 2nd Edition Advanced Dungeons & Dragons ruleset.

Cities in Motion. Maybe I'm just not good at it, but the game seems very flawed. The basics are there, but there are little things that show that the game wasn't polished & play tested enough.

-Only the metros work kinda like they do in real life. With buses and trams, if the line is more than a few blocks long, people will start to gather at the stops, and eventually be unhappy because there's not enough buses for them. I've never seen a bus stop in real life, even next to a crowded mall, where 300 people will patiently wait for a bus to come: they might be upset, but they won't leave until a bus picks them off one by one. Even if there's a perfectly good metro station right next to them. There's no making rational lines in this game.
-Occasionally stupid challenges. A random person often proposes a deal, for example: "dude, us students really need, like, some transportation to get us from the tenements to a college. Can ya help us out?" This really was a challenge that appeared at one time, and since I wanted to make them happy, I built a bus line for them. I got the reward after transporting 20 students. Want to guess how long it took for that challenge to complete?
Four game years. To transport 20 students. Like, why the hell are they asking a line such as that if they never even bother to use it? Also, one time some bitch wanted me to make her a line from her house to the city. How many times did she use the completed line? Zero. I had to close the line a little bit later, because no-one was using it.
-Stupid main quest givers (or whatever the people are called who you're supposed to help during the scenario). This german guy at one point praised my underground metro for its efficiency. But the thing is, I didn't have any underground metros at that point. Only ones that travel on elevated tracks. Also, in a scenario in Amsterdam, the final challenge was to remove all vehicles with poor condition. At that point, I didn't know how to tell which vehicle was in poor condition, so I removed almost all of them. After that, the lady told me how good the public transport system is now, even though only a few lines had any vehicles assigned to them anymore. She also complimented me for completing the scenario without using any metros. In reality, metros made most of my cash flow in that scenario; I just removed all the lines and stations because of that challenge. One last example: the final challenge in another scenario was to raise 50k in cash. Can you guess how long it took me to accomplish that? About 5 seconds. I simply walked into a bank and took a 50k loan, even though I was already way over my head with all the debt I had. Despite that, the quest guy praised me for a job well done.
-Easy to cheat in the game. Want to make a lot of money? Here's a couple of things you can try. 1.Wait for the metro doors to open, then raise the ticket prices to the maximum of 99.50. The customers will get upset, but they'll still pay the money like sheep. 2. Someone asks you to make a line, but isn't very specific about it? Make a bus go around the block, collect the reward, then remove the line like it never existed. 3. Have as many loans as possible. When the scenario is finished, they won't care if they are way over their heads in loan debt and looking at a company that doesn't make any profit, and is on the verge of bankruptcy. "Hey, at least we got a solid transport system, right?"
-The game's also very repetitive, I'm on scenario 6 and I feel I've seen it all already, and have no real desire to play the game anymore.

It's a shame, I really wanted to like the game. Well, at least I didn't have to pay anything for it, because it came for free for completing that one Paradox Survey a few months back.

Max Payne 3 and Dragon's Dogma

I am currently playing through:

Tex Murphy: Pandora Directive.
Thief 2: The Metal Age.
Splinter Cell: Pandora Tomorrow.
Shadow of Rome.
Baldur's Gate

At the moment:

Deus Ex Human Revolution - About 18 hours into the game, really enjoying every moment of it, definitely deserving of the Deus Ex name. The environments and the overall design of the game are very immersive and seem pretty consistent.
Out of the Park Baseball 11 - Getting back into this game, after buying it last year, so far just a few games into my first season, and already beginning to struggle with my current roster. Only 3 players are hitting above .250, it's going to be a big season for transactions for my team.

Upcoming:
Mirror's Edge
Thief II - Had this on disc, so decided to fix it up to play on my Win7 laptop, and voila it works!
Portal 2
Tom Clancy's Ghost Recon
Tom Clancy's Splinter Cell

Star Wars: Knights of the Old Republic

Proun

Just finished Broken Sword 1 yesterday.

Now I'm debating on starting up Fallout. I've played Fallout 2 and Fallout 3 (both many times) so, I thought it might be time to start with the original.
