But BoF4 (From what I've played, which is the first 30 minutes) sucks.
3 is way better.
Can you really judge a game based on the first 30 minutes?
That being said, I think thats about how long it took me to form my opinion on the game. We all have an opinion though. I will agree it's not the most solid game ever. I just like how it was presented and the feel. The story, although pretty cool, was kinda shallow, and there wasn't any real solid character development. I really enjoyed the asian/chinese theme going on. In my opinion. The style that game was created in, should have been where they were with games like final fantasy 7 and 8, instead of trying to push into 3d so early and roughly. It's sort of a game-crush of mine.
BoF3 also kicked ass. That game is a classic. I am actually playing though it again right now. However it still suffers a lot from the same things BoF4 did. Only without certain things I loved from four.
Anyhow, thats just my opinion.
