Which is why I asked what kind of themes you DO like :P Saying what you don't like helps, but you'll probably get results you're more satisfied with if you say what you do like.

Hell even listing (purely an example) anime you like could help with recommendations.

What I would do to just get yourself started is go download steam and try some demos listed under adventure, puzzle, or role playing and see if there's any you like.

Welcome to Steam

I could list off several titles I think are really good, but I don't think that would help much.

If I was to just name some PC games off the top of my head I would say...

Dragon Age: Origins (does involve violence, but heavily fantasy based)
Elder Scrolls IV: Oblivion (again violence, but doesn't even have blood, lots of fantasy)
Mass Effect 1, and 2 (again... there is violence, but not brutal violence. Cartoon violence. This is sci-fi)

You could also try MMOs such as Ragnarok Online, World of Warcraft, EVE Online, Maple Story, or LaTale to name a few.

The sims 3 seems like a good pick.

Dragon age origins, seems like a good game, well all my ladies friends love it.

if you have a wii.....
 

i love animal crossing - city folk

and i know plenty of guys who play it. but you would probably describe it as a "girly" game. it's hard to explain. probably better to google it.

and if you do get it let me know and we can be friends on it!

what about myst or something like that? that's an old one, but they probably still make it or have a new one out like it. i'm a little, ummmm, older :)

I played Ragnarok Online myself for some time, actual it was my first game I really played for a longer time that was five years ago. If you have some people to play with it's really nice. I had a cool guild back then so it was really fun.
I can recommend that game, but it's not everyones style.

Hmm...

Nitendogs for the DS. :3
