@Garnett......... Sonic 1 & 2 are on xbla but not sonic 3.
If Sonic 3 comes to xbla i will still buy it as a standalone game despite the fact that its also going to be on the Sega megadrive ultimate collection.
Same thing if they ever released Streets of rage 3 standalone aswell.
Some games are just so damn good they are worth owning twice (Three times in sonic and streets of rage's case cos i also have them for my Megadrive).
I don't mind Sega milking their franchises, afterall, they are one of the greatest developers of all time...!!!!!!!!!!!!!!!!
