I don't understand why resident evil 4 is often times considered the best in the series and 5 the worst. As others mentioned with the introduction of 4, resident evil changed from survival horror to an action game that just happened to include zombies.
Anyway I'll probably get resident evil 6. The only thing I hate is the fucking gun weilding zombies. Biggest reason why I felt ninja gaiden 2 and resident evil 5 were lame. Giving random enemies guns when it clearly makes no sense for them to have guns is such a lame and boring way to make harder enemies.
