Gears of War on PC ?

Sweet

Quote from von*ferret

jumping doesn't really benefit the gameplay though. The idea is hopping from cover to cover to engage the enemy. They have leaping over cover, but honestly jumping would just quicken the gameplay.

I wouldn't use "quicken" so much as "break."

Jump is more frustrating a feature than it's usually worth; if you can get the same functionality with context-use scenarios, you win. It's not really a requirement of anything save for platformers - though twitch DM games certainly make good use of it too. And Crackdown.
