At least there is a spell to restore it. In classic Wizardry, the only way to deal with level drain is to regain the experience and level up as normal.

In Wizardry 5, MAHAMAN can reverse level drain from enemy attacks, however that spell has the drawback of level draining the caster.

Elminage Gothic is also like that.

The problem with such romances is that they're just overdone. It feels like they are inserted into every single book/movie/game, even where such romance doesn't belong.

It depends on amount of books your read in your childhood, I guess. Heroes, princesses, dragons and stuff =)

There’s even a stealth section in Octodad. This guy is about as stealthy as a heavy metal band.

- Bad voice acting ( No matter how good the game is I just can't play it if the voice actors/actress are bad at their job)
- The illusion of choice( Telltale games comes to mind) what's the point of trying to use different dialogs if that guy still ends dead and nothing changes?
- Quick time events( I'm looking at you, Yu Suzuki for starting this)
- Bad checkpoints, or games where you can't save unless you finish the mission
- Bugs that break the game ( *cough, Bugthesda, cough*)
- side-quests that lead to nowhere
- trial and error in a game which wasn't supposed to have

Someone should get a design patent on privileged lesbian teenagers as characters. In mainstream gaming (beyond noncommercial and semi-commercial "true indies", mods, amateur games made with kits), lesbians are oh so conveniently young and waifish, so as not to suggest that gay women can actually be independent and competent and same-sex attraction is more than a phase of "experimentation" and haywire teenage hormones. In Lolita, there's a scene in which the viewpoint pedo fuck thinks, "Omg, I thought the teen I've raped had only engaged in innocent meaningless lesbian diversions, but turns out she actually had real p-in-v sex!" This is the attitude shared by mainstream [allegedly] queer-friendly games. Do not want.

Bosses that "warp" all over the level. You're just about to win the game, then the boss all-of-a-sudden gets this ability to jump randomly from one place to another!

"Checkpoint-only saves" is another bad trait. Even the original Wolf3D allowed the player to save at any time, yet in almost 2016 we still have to deal with checkpoints!

Yeah, this drives me up the wall to. If the choice doesn't make any actual difference to the end result, just leave it out.
There are so many games I've played where I've wondered would it make any difference to answer questions differently or if it's just for my own entertainment...
If you want choices in a game make them big and actually count (or at least make the small ones cumulative and have an effect at some point, so choosing to be bad all the time makes some difference to the story)

Quick time events. Just let me watch the cutcene in peace!

A long, unskippable cutscene just before a frustratingly difficult boss battle.

Quick time events.

Being forced to solve all conflicts with violence, at least some of the infinity engine games give you the possibility to use more peaceful methods instead now and then.

Unskippable cutscenes/dialogue.

Rare or complicated saving methods, worst case: GTA2. It completely ruins the game.

Simple and unrealistic characters with just one motivation and no inner conflicts at all.

Enemies that just pop-up out of nowhere, especcially in FPS.

Constant romancing in RPGs. Seriously, those characters have usually more important/urgent things to do.

Politics shoved into games, like
- the usual American army glorification (I really hate that)
- an increasingly unrealistic amount of homo-/bisexuals just for the sake of current gender politics instead of just having a representation which it often claims to be - you can't represent a minority by making it bigger than it is.
I'd like to see my own minority represented too (which usually isn't the case), but not for the sake of it and not making it seem forced.
- one sided view of nations and related stereotypes if not meant in a humorous way

No free choice when it comes to the screen resolution - a lack of this doesn't make a game age good at all. Screen sizes and aspect ratios change over time in several directions.

Restricting invisible walls ("you are leaving the combat zone, yadda yadda").

No enemy variety (Trine 1), no level variety (The Ball).

Controller oriented controls of formerly PC-only series (!).

No button mapping, no non-M$ controller support.

What do you mean by "turn based controls"?
I played Final Fantasy and don't remember any such sequences. Maybe you are referring to one of its "sequels"? ("sequels" is in quotes because the games in the series aren't actually connected.)
Have you played Undertale?

Or maybe not. Then again...

I mean TBS.

What do you mean by that abbreviation?

You're joking right? There is an entire gaming genre called TBS and you are asking me what it means?

WTF is it April 1st already?! :P
