I got this today

I'm almost halfway done the main quests now.
It's very very similar to the first game - same main characters (plus a new guy!), the basic gameplay and zombies are the same. It's a new island but it's similar, so far I've just been running around in the jungle like before. Overall I think it's harder, definitely you get more zombies than last time. I chose not to import my character (because I wanted to play the new guy!), but it still starts you off pretty difficult. They do give you starter skill points to build your skill tree, though. And I find my weapons degrade more slowly.
Riptide has boss fights along the way, which is cool! And more group stuff -- you fight hordes with the other survivors, who can actually fight back unlike the original, so you can run around and help whoever needs it. This feels like online co-op to loners like me that have nobody to play with

Graphics are about the same, so far I've had no glitches. Apparently on Steam the co-op isn't working :s
Overall I like it

sorry for te ramble but I'm excited it's finally out and I wanted to spill my thoughts
Waogo did you end up importing a character?
