I still find it funny how everyone always brings up these Gears topics even if it's just one or two minor things, and Gears of Wars openly admit the series was inspired by Resident Evil 4. --- Only if you pay me.
It does matter since each character seems to have a different playstyle.
Leon's seems more like an evolution of the classic formula, Chris seems to be an evolution of the action-survival formula (which includes cover), and the new guy seems to have a twist off of Uncharted-style gameplay. --- Only if you pay me.
