Most of the games in this collection are old Sega Megadrive titles but, in a bizarre twist, Road Rash, Road Rash II and Road Rash III do not contain any of the original, classic music by Rob Hubbard. Instead you get some awful, looped dance music. In Road Rash I & II, there's not even any title music! It's even more strange, considering that none of the other games in this collection have been tampered with like that.
Desert & Jungle Strike are pretty much intact emulations of the old Megadrive games, although there are some problems with some of the sound effects.
Budokan is still very very boring and unresponsive, just like the original, but great for a nostalgia trip.
Syndicate is fun, but tricky (I always preferred Syndicate Wars myself). It's not the PC version though, it's the SNES version.
Mutant League Football is a great take on American Football and The Haunting is quite original. Again, these are the Sega Megadrive versions.
I never played the rest of the games in this compilation before so can't really compare them. I mainly bought this collection for some Road Rash nostalgia and EA have ruined that for me; hence the low score.
