Weaknesses because I like them:
I love create-a-character games. The ones that allow you to go full out on someone's face, hair, clothing, color design, body type, etc. I know people criticize some elements of Saints Row the Third, but I honestly liked its create-a-character more than 2's because of 'how' I was able to make characters.
I go nuts for cel-shaded graphics, probably because I'm a big animation fan. Any game, not matter how bad, will always get a 'might as well check it out' from me if it's graphics are cel-shaded.
Also, jetpacks. Because jetpacks.
Weaknesses because I hate them:
One-click combat..........RRRRAAAAAAAAARRRGGGGHHaepaienfa;oekfnaief
I cannot think of anything so boring, so stylistically uninteresting, and so uninvolving forthe player than to just press one button, and let the game play itself. Its why I can't get into some of Bioware's more D&D style RPGs like KOTOR, Baldur's Gate and Dragon Age Origins, because I simply have no enjoyment whatsoever with that retched combat system.
I am horrible at strategy games, whichever you can name. I suck at RTS's, and I suck at more RPG-like strategy games like Fire Emblem, Final Fantasy Tactics, and Advance Wars. My characters for those tend to get shitty stat upgrades upon leveling up, and I usually have bad luck when it comes to attack accuracy. And I'm someone who doesn't like having his units die, so if one does, its a restart for me. So I really don't play those.
