I've recently started playing Arcanum Of Steamworks & Magick Obscura, though not for nostalgia purposes, since this is my first time playing it.
I want to replay Baldur's Gate 2 in the enhanced version, and since I didn't get very far at all with BG before skipping to the next game, I want to get the enhanced version of that too. Unfortunately, I'll probably just end up romancing Aerie again, as a crusader, so it's hard to get myself to play it (plus I would need to buy the enhanced version). That's also why I haven't played Fallout: New Vegas a 2nd time. I'd end up either playing the same character, or playing a different one, wishing I could play the same Courier I did before.
Chances are, I won't play it a 2nd time either, because I don't think I could get past playing my b!tchy elven supermodel. Even with the mod that makes the screen wider.
