I'm starving for an open world rpg especially something to tide me over until skyrim. I have one question. Can you backtrack to all the islands? I've read there are four islands and you unlock them as your progress through the story but once I leave the first island or second island can you go back? Or are you stuck on one island at a time?

I'm assuming you can. Don't hold me to it, however there is an active thread on Two Worlds 2 http://www.gamesas.com/index.php?/topic/1156754-two-worlds-ii/page__st__20__p__16945882__hl__two+worlds__fromsearch__1#entry16945882

Use that one, please.
