I don't want to reserve the game and play the beta incase it doesn't work
BTW, just to make this clear:
Sins Beta
Two was more stable and more enjoyable than most released and "finished" games out there: in fact,
every sins version I have played has been as stable if not more so than any
finished Blizzard title, ignoring certain "special circumstances" crashes (Save games in multiplayer in beta 3 comes to mind...). Yes, there are more errors than I'd find in a Blizzard title -- for example, the stringID issues which still haven't gotten fully fixed -- but I've had more out-and-out crashes in World of Warcraft than in Sins. A lot more. Even for a finished product, this
Beta is not only rock-solid, but darned fun!
