Hopefully no technical drama will occur not that I won't be expecting problems from a game that isn't finished (that sounded a bit snobby but it wasn't my intention).
Not at all. You’re right to expect bugs and niggles. The game is perfectly playable but far from problem free as well as being incomplete (we only get part of act 1 and it now looks as though there’s going to be no more story until the full game is released). Still totally worth it in my view, particularly if you’re keen to try out some of the different races and classes to see what you enjoy, though, as you may already be aware, you’ll need to create new characters when the full game comes out.
