I think you don't understand how this works at all.

Metal Slug 1 and 2 PLEASE

Games from big publisher, remakes and such don't need to be greenlit by the community, but negotiated with Valve. This is for indies only, not a wishlist like Gog's.

command and conquer red alert 2 and yuri's Revenge? windows 7 Online playablility :)

Baldur's Gate 1 + 2 of course.

yes that is what i would like from this

Steam + GoG merger please :P

Mega Man and Mega Man 2

C&C 1 from Win 95 :D Kane's ending is yummy

Freaking Starbound ( For who that doesnt know it yet : Some kind of Terraria, developed by Tiy and his team )

yes, Metal Slug and Read Alert 2

would like Ultima 7 + serpent isle to be added, and dunno, maybe some old arcade games as well? i mean, they already have some megadrive games in the list, so why not arcade games like the simpsons, TMNT, TMNT IV turtles in time, golden axe, bucky o'hare, etc etc

Resident Evil, Resident Evil 2, Residente Evil 3, Silent Hill 2, Silent Hill 3, Yu-gi-oh: Power of Chaos, Rockman X4, etc.

its up to the makers of the game to put them up, valve isnt adding any game to greenlight by requests

I'd like to see Toonstruck, Grim Fandango, and Urban Terror on Steam. Odds are.....none shall pass.
