I bought it a while ago but didn't play it immediately, then I heard about the big update coming so I waited for it to play, then this update got two revisions in about as many day. So I still haven't played, I do not want to encounter a big bug or have to relearn or unlearn something.

Is it safe to play now or will there be another update Monday?

Uhh. Another minor update.. again. I should wait the final update before downloading (again) the installer. For now I guess I'll just update the game through galaxy client -even though sometimes it still doesn't work at all.
