-Lower loading times
-A color other than grey, brown, grit, gunmetal, dirt or grime, seriously, I love the vibrancy of HD and devs are just not taking advantage of it.
-More creativity in games instead of the re-skins of previous games that developers seem so dead-set on releasing. You can add all the new weapons you want but if I feel like I haven't changed the disc in the console you have failed
-Less frequent, smaller patches
-Smaller teams, lower production budgets and longer development cycles on games. We really don't need a new Call of Duty game every single year.
-Stop putting retarded forms of DRM on the games, I don't care if you want to bind my CD key to an account, but making me maintain an internet connection is stupid, (Yeah I know this is a PC problem mostly but I'm tired of it and would like to see it disappear during the next-gen of gaming)
-Also miss games that genuinely required some skill not just an inordinate amount of time.
-Stop charging Retail prices on digital copies in the store
-And for the love of god can we go back to games where I could buy the game, unwrap it, put it in the console and be playing it within a minute. Tired of getting a new game only to have to download a day-one patch then accept a EULA, then have to accept something else
