I played the original in '96, and worked HARD to get every single gem, for 100% completion. I was worried that they would muck-up a classic - but CB4 is like a reboot + tribute - the best parts of the original, and sequels - with some new game mechanics that are awesome. And the graphics are incredible. I've been playing play+pass mode with my 11 yo (on death or checkpoint) - has been heaps of fun. There are 43 levels - and - can play in FLIP mode afterwards. And then time attack mode. This is the best CB game in the series - fantastic game...!
