Skip the original; it's horrible.
Sorry, I'm not supposed to say that. But I'm not a huge fan of games that require you to attempt each part of each level about a dozen times so that you time everything correctly. How anyone plays it without an inifinite lives cheat is a mystery to me
.
The rest are great, though. Well,
Rayman M is a bit lame, but
The Great Escape and
Hoodlum Havoc are definitely ones to play.
