Meh, just looks like Fallout 3. They show the combat, but jesus, the mutants are getting gunned down and not even flinching until they suddenly explode. I guess fans of FO3 will be happy, though.
I can understand people asking "why change something that works?", but that it just progress, which is important for the industry. If people keep buying the games, great, but with that attitude we never would have had Final Fantasy 7, Resident Evil 4, Super Mario 64, and what have you. Things can always be improved.
