Well, I got though with the demo yesterday. It is an awesome game, even when not compared to it's predecessor. There were only two things in it that made me sad:
1) Leon's gone. :(
2) No more suitcase. :(
Other than that, though, it's really cool. I noticed a lot of really nice touches they added. There was a pretty good "Are you kidding me!?" moment I had where I thought I was safe by running onto rooftops, only to see the zombies climb up, and jump over at me from every direction. I suppose the radar is a nice addition too.
For some reason, I don't really like it when games are set in extremely humid areas such as Africa.I like it when games have cooler enviroments (colder), and I honestly don't think it fits the a horror game to have it in Africa. But, whatever, if anybody can make it work, it's Capcom. And if the co-op works nearly as well as it did in Left 4 Dead, consider me sold.
