Purely for the fun of it and to pass the time. So don't take it the wrong way, whats peoples favorite aspects are from any different MMO or RPG
here's mine:
1) For PvE NPC size and scale, and interactivness of fighting the likes of dragons dogma
2) For PvP ESO of course, masses of enemies siege equipment going off, chaos and destructive environments, skirmishes, tactics, decoys, it has it all, oh and large scale battles
3) For the rewarding gameplay in an MMO the mechanic of a DCUO "celestial-healer" (combo mechanic)
sorry no pics. basically you press a button you do a move, classic mmo, in the case of DCUO celestial healer/dps gameplay before the move ends you can press other button sequences a bit like pulling off a combo move in a "beat em up" and combo the initial move into a more powerful follow up move all off the same initial resource cost, timing is key you dont just press it as quickly as you can you have a window within the animation.
never played an MMO ever with such rewarding PvE gameplay remembering all the combos, timing them right so you dont have to cut short to burst heal the tank, pulling it off and solo healing 8 man group content watching animation and the health bars both, ...and the feeling when you pull it off. shame PvP was lacking
4) For combat animations making you feel Bad A** it has to be Assassins Creed
5) for the size of the Map and free roaming freedom: skyrim of course
6) For allied NPC comradeship, and interaction - Dragons age / mass effect always deliver
