Diablo and so called " diablo-clone " MMORPGgames are considerate action , and are NOT like 4s because Each CLICK equal's an Hit, Or Hold to keep attacking and once finger is off the mouse it stops, where as most 4's games are click, and it auto attacks and the only manual attacking you do is spamming the 1-9 keys, not necessarily different combo's.
Using the Click per attack feels like you have more control over combat IMO where as standing still , with auto attack and pushing 1-9 keys with a cool down seems to robot for me. ( guild wars 2 will be different aswell considering its 1-9 keys, but has an action feel like )
Return of Warrior is open world, Medieval themed, Rpg. You do get alot of options in this game from healing classes, enchanting classes, to tanks, and high dps assassins and archers. It's pretty much party oriented, but it's not too bad soloing.
