#29: This game developers planned to create an evil version of a famous female character.

You were fast, Crazy Taxi it is!

30- Mega Man X


    I will post the hint for 28 once again: A mirror plays an important role in getting the good ending in this Metroidvania.

    Now for 27: There was a lot of drama over the localization of this game.

Xenoblade Chronicles X?

#30. Beware the little girl.

The Last of Us.

I got stuck because of Ellie once, evil brat made me have to restart the game.

Is it BioShock? No wait! It's F.E.A.R.

Yep

No, but you were pretty close with that one.

The first Xenoblade Chronicles then, for some reason I was thinking about the boob-slider when I read your hint.

#30 Assassin's Creed II

After the first Assassin's Creed turned out to be a slight disappointment, the second game proved to me that the series could be genuinely great. The main character is still the best in the series, the gameplay was vastly improved, and most importantly given significantly more variety. This was also still at the point when they hadn't added too many pointless gimmicks to the games, which already started with Brotherhood, although that is still an excellent game as well.

Hint for #29:

The game for which Nintendo basically created an entire controller for.
