While I thought Red Dead Redemption was a wonderful game, it was a shame they devalued the power of their own guns by giving you nearly unlimited ammo and nearly unlimited enemies to use it all on. By giving you crappy guns every shot felt so much more powerful, crafting negative space around every action that I thought complemented the atmosphere in spades. Scavenging ammo off of corpses was also meaningful, every fight buying John a couple more bullets to last him a little longer, until you didn't need ammo anymore, and then it was suddenly everywhere and you never ran out. In a way Max Payne 3 improved on this by making you count your bullets (sometimes), but you're still killing so often that the act starts to mean absolutely nothing.
I want my action games to borrow from survival horror- take away all of my handicaps and make me feel like I've earned my victories (make them more like Godhand?), not just "pressed A" as everyone has been saying. Having four powerful bullets and having to plan their use is immediately more interesting than having several clips in my AK-47 and just pointing at enemies until they don't get up again. Especially when you have to plan ahead because there's no promise of any of the things you want or need in the future.
