I was so pleased to hear about this coming out, especially after owning SEGA Classics on PS2 and writing a rather harsh but true review for it on Amazon! This is an absolute blinder of a SEGA comp and they have truely redeemed themselves by putting 27 titles, which include a large percentage of great well known games (Sonic 1 & 2, Ecco The Dolphin, Golden Axe 1,2,3) and not so well known classics (Vectorman 1 & 2 and Ristar) on one UMD with spot on emulation that pretty much mirrors the original quality of the games and audio soundtracks, unlike the EA Replay comp, in which they emitted the original Road Rash music (WHAT!?). Yes its a shame Streets Of Rage isn't on here but they're probably gonna release another one with that on, Can't wait for that! Also it has improved since my initial assesment as the new psp has a much better d pad for retro similarity, for those who prefer not to use the joystick. But overall I cant fault it, and you can pick it up for less than a tenner in some places. Bargain, and one of the best retro compilations around! BUY IT!!
