IMO these two games can't be compared, it's like comparing a submarine and a plane because they are vehicles..
I see that some people don't understand that the tank controls in RE4 were deliberately designed that way. Think about it - if the controls were normal, the game would be a walk in the park (like most TPS/cover shooters).
Furthermore I don't understand why people are saying that RE4 revolutionized the genre - how? For example the Max Payne games came long before RE4 did, and there were no other games like RE4 released after, hence why it is still so unique to this day. The game that revolutionized the genre was Batman Arkham Asylum in 2009, now that was a game whichs mechanics everyone hurried to copy.
