l2 maybe is good on privet but retail always kick ass. WoW retail its not much right now u can gte battlechest for 8£ and u can check the game out in proper way or free trial like 14 days or something. For example dungeon finder is not working for about 80% priv. servers out there. So in my opinion to try game like i did, WoW (finish on T10 :P) Aion lvl Glad 47 and L2 DK80 ES80 HE71 :) (yes i did waste my life and am happy about that) u need to check out retail server of any game you want to play!
ps. sorry for my bad english but i dont give a S**T
