I must say that "tutorial" part is quite long and probably turn off many ppl that arent that interested in the game. It sure does hell of a job to keep gold spammers out.
As for game after that its really fun. Everyone can find someting for themself as long as theyre into fps
2PvE modes (dont count solo only ones) and alot PvP ones which are quite original.
I also like how you can use premade classes and dont bother with buying equipment/consumables. Or go for custom and get to choose and buy everything yourself. Or switch between those whenever you feel like.
And theres ofc steam trade for those that are interested.
