sorry lol whats better, 3 or new vegas?
Dead rising.
I love it, the endless amount of fun chopping zombies up with various silly weapons. Control method is not to everyones tastes but god I love it. It was the first game I bought again when I got my 360.
I think that's a very personal question and the answer will differ depending on that persons opinion rather than which game is technically the better.
Personally I prefer Fallout 3, it's my perfect game. It has realism but not too much so as to make the game boring, it has a good story, tonnes of side quests and crucially the ability to play after the main quest has finished. I understand why this isn't possible in New Vegas but it still bugs me. I can't really put my finger on the exact reason, but I get a nice feeling when I complete the main quest in a game, I liked to know that the story is finished and I can then move on to the side quests, rather than being forced to leave the main story hanging open if I want to explore the world further, like in New Vegas.
I prefer the Capital Wasteland to the Mojave too, it has the perfect atmosphere for me personally, that isn't to say New Vegas is a bad game because it's sublime, but for me Fallout 3 & DLC remains above it.
I had exactly the same thought when I read the thread title, didn't expect it to be the first answer.
Dead Rising, it still looks good and has great replay value.
A bit of a learning curve at first I guess, once you get over this though it opens up to a great game.
My only problem with Dead Rising was the hideous screen tear when played on my monitor...
I think it's got to be Assassins Creed 2 for me. Not sure why, just really enjoyed playing through that game.
