I've been playing for 4 years...I still play because I have many choices...I can go into a town or out in the boonies and just stand there...or I can get into a lot of delves...many of which end up being over my head in various ways...and somewhat stressful. I like crafting and looking for mats. Selling stuff.
I usually find some way to improve a character or something new to try.
As compared to World of Tanks...where if you are not right on top of your game...your experience is not fun...and the stress level is so high...it's like rolling a boulder up a hill where you never get too the top. You can win...but you never really win...
