I think Gothic 3 is worth playing as it is right now. (Don't have time to wait anyway).
The problem with gothic i have is that i think the fighting can be tedious sometimes.
Have had one crash since i installed it friday. No crash bugs and not anything else than the usually frustratning gothic feeling, which tends to be a incredible satisfaction when you accomplish something.
Am in an interesting part of game right know and wish that more people play it!
