I've been a fan of open-world/sandbox style RPGs since the early 2000s when I sat down and played Morrowind as a 12 year old boy. Since then I have progressively begun to enjoy them more and more. Now they are basically my favorite genre and every time one of the major titles comes out, I am on it for 100s of hours. Borderlands 2 is no different. I don't really have much to say about it other than that it is fantastic. If you liked the first one, you will love this one. Its better in almost every way, in my opinion. The only gripe that I have is that assault rifles are not nearly as good as they were in the first, nor as easy to use. Other than that, its pretty awesome. And its an easy 1000 gamerscore if you care about that.
One of (if not the best) game I've ever played. The expansions are well worth the money. They're not just a few thrown together things just to get your money. Been playing this game for 2 months and I'm still not tired of it.
