To kick it off:
My personal top 3:
- Puzzle Quest: discovered this a few days ago and man is that addictive! Bejeweled meets RPG and somehow it works like a charm. Although there are RPG elements they're not the core of the game imo. I tend to click away the text and just play another battle. The great elements taken from RPG are the spells that you can use to manipulate the 'bejeweled' board, which keeps the game always interesting with new options.
- Zelda, phantom hourglass: good old Zelda adventure, nothing much to say about it really
- Mario Kart: Bought this because of the high reviews and although I usually hate racing: this game is addictive. Not your classic racing but more a cartoon take on racing. With cups and time trials this is very addictive as well
