a new PC game for my wife?

Bejeweled 3 is very good--the unlocked special games are better than the initial games; you unlock them with a reasonable score. It's challenging in many ways; quests, milestones, badges. A lot of fun. Nice music.

I second Skyrim. There is violence but the game is incredible. Whatever you do, don't get her World of Warcraft. That is a hard addiction to break.

portal as mentioned before is a great puzzle game that will keep her occupied whilst you uke for ages

Skyrim is really good. i bet she would love to play it. If the likes star wars she should start with star wars the old republic. I know many girls who play this game! But of course if she's not too much in to RPG games this could be problematic. I also would suggest Alice the madness returns, it's a really nice game and Alice changes the clothing after every level. I realized that many girls appreciate this

Portal, civilization,
Basically check out Steam's puzzle category.

If you're looking for the worlds most addictive time-vampire of a game, that will guarantee you hours and hours of peace & quiet to practice, get her Minecraft.

I would recommend World of Goo. Look it up. Much like PvZ, it's got a very cool, cartoony interface, has a basic principle but can get very challenging.

Give that a go. Great fun.

On Spore you can make your creatures as cute or ugly as you want. May be a bit too in depth though.
