Looking for recommendations

[Uncle Yuan]

I'm looking for a new game for the XBox360.  I'm kind of particular about games - I'm not super into twitch games, although I don't mind shooters in general.  Games I've liked so far - MUA, Portal, Bioshock, HL2 (although the finale of Episode 2 is too twitchy, I haven't been able to beat it and I got sick of trying).  My son is really into the Lego (we have Star Wars and Indiana Jones) series and I've tried them, but they just aren't grabbing me.  Really, when it comes right down to it I tend to put the games on the easy setting because I find that I enjoy the story and exploring the setting above the action.

I'm not above trying other genres, either.  I have Forza (came with MUA), but I haven't tried it yet.  It's supposed to be good, though.
