I played the open beta for a while.
There's a pretty common complaint among reviewers/non-hardcore Wildstar fans that the early game is a slog.
It was too much of a slog for me to want to give them money. I kept waiting for that magic moment that fans of the game say comes once you get through the early levels, but it never arrived. I think there is probably a good game in there somewhere but from my, admittedly limited, experience with it I couldn't get into it.
