Agreed lots of potential for this game. The setting/location was really nice and with the best cast of characters Claire, Chris, Steve, Alfred, Alexia, and Wesker. And even got a awesome mix of enemy variety and bosses.
The bad things from it were they have all the great material but didn't do it as well as they could have. The gore was toned down from the pervious games, the backtracking and replay value wasn't as good as RE1 to RE3. There's some things that you could easily missed or messed up without knowing beforehand that you'll switch to Chris. More chance to get snuck like the Tyrant plane boss if you didn't save up for explosive bolts or got bio gas rounds etc. But all this they could easily fix in the remake which combined with the amazing cast and great story is going to make a top tier RE game.
