Actually, I probably should have known better. He played ME1 and managed to get through a couple planets of the main story, but then he got bored and quit. I just asked him about it and he says he liked the game, but it had way too much story.
Then normal-style RPG's probably just ain't for him - I do know people who are like that and just don't really want story and long-winded dialogue sequences in their games. They just really like controlling the action and action-orientated stuff.
He might like ME2 over ME1 b/c there's a lack of inventory and its action/combat is a lot more satisfying in comparison to the original. Though, ME2 does have plenty of dialogue and decision-making stuff - and that stuff sounds like it might NOT be up his alley.
If you want to give him some sort of RPG - I'd probably suggest ARPG's. Diablo II is one of the best, when it comes to that genre - and even if he got an old rig, chances are he could probably run it; especially since he runs WOW.
He's spent a lot of time with CoD4 and MW2. He bought Borderlands and Bad Company 2 when they came out. He sold Borderlands as soon as we beat the story, and sold BC2 after about 2 weeks. Other than that he pretty much just plays MMO's, and he started with WoW. He played Warhammer with me for a couple months, as well as Allods Online (free to play game).
Borderlands isn't dialogue-heavy - so I bet that's why he dug that. It's a blast just to play.
To be honest he and his other close friends are weird to talk to games about. I mention id Software or Duke Nukem 3D and they have no idea what I'm talking about. I mention Final Fantasy and it's not even "yea, I started with FF7", it's "I started with FF10, and that's the best one". I don't know if it's that they're all in their early twenties, or that they just never played many games before WoW and MW.
I'm in the "Yeah, I dropped off from FF after I finished FF9" group - hehe.
About DN3D - that's a freaking classic FPS. I bet your friend might like that game - "balls-to-the-wall" non-stop action. Though, if he's anal about the fact it might look very dated graphically - he'd probably be better off looking at DNF, if and when they really comes around - since that looks much-more graphically modern.
