If you've done all you can in Skate, then it's worth picking up to extend your adventure. For newcomers, it may be better to try the original first and just spend time skating around and learning all the tricks on offer. Maybe it was because it was something new, but the original Skate was a much more enjoyable experience. Skate 2 builds on that, it just can't quite capture the magic. But don't let that put you off, it's a hard task matching Skate's high expectations.
