Pretty much what you'd want and expect
Visuals are amazing, sound is amazing, and while I've only played single-player so far, the co-op is something that I'm looknig forward to trying.
I'll admit I was never really into the Resident Evil games much until RE4 came along and this game does seem to build on RE4. Maybe it's not quite as scary....but I think that has alot to do with games like this just becoming more commonplace now so it just doesn't seem as scary to us. However, my daughter and wife were watching RE5 and they sure thought it looked pretty scary....
I can understand a bit how those looknig for a vintage survival-horror game might be a little let down....but I really think Capcom would've been going backwards if they tried to make another game like the original RE. I was looking mainly for an extension of RE4 and I think this game is a logical progression.
Overall, the game really just seems to have what I was looking for and I'm pleased with it. Great visuals, sound and I like the overall tempo of the game. If you are looking for something different than RE4...well, maybe you should stay away. But if you enjoyed that game and want more, then RE 5 should satisfy.
