Really fun!
If you play on the "retail" servers (even though the game is free) there are ALOT of botters and almost no GM's. So after a while i got really pissed off when a botter came by and stole my kills, so i started playing on a private server!
The server im playing on is a 30X rate server so the game wont take long if you want to be high lvled. This may seem boring or somewhat like cheating, but its much better than competing against bots. Also because its a private server, u can count on the gm's being there and therfore the server is MUCH better!
The bad thing about this game is the gear, if you have played mmo's like WOW or such, this will be a lettdown. There aren't many weapons / gear in general, so you will see alot of guys running round looking the same, but if you can look past this the game is REALLY fun!
I would advise you all to give it a try!
