So it took me an hour of frustrating clicking just to get logged in. They had serious login server issues with all the preorders attempting to connect at launch time. I suspect this could be an issue whenever they restart their servers. Hopefully they iron out that issue.
Once I got in, the game was flawless. No lag, no camping, no griefers, no problem. Once during my 12 hour stint, the mapserver dropped us, but I was able to reconnect instantly.
I made it to level 10 blaster. I also created a couple play characters... a tanker and a controller. The controller looks fun. I'll have to try out the other types too.
Anyway, for the simplicity of character progression, this game is quite fun. No equipment or stats or skills, but you do get the choose new powers as you advance. The costume creation is a fun game in and of itself.
