I started playing Borderlands 2 recently, but then moved on to DOOM 3. Still got Borderlands 2 to continue but don't seem to be in any particular rush. Maybe I haven't given it much time yet but I didn't see what all the hype and fuss was about.
Yup, got all the trophies in the first, working on the second. I like it a lot. I'd recommend getting the first one first mainly because it's only like $20 compared to the $60 for the second.
