It's multiplayer but it feels more like a rpg than mass effect and latest bioware stuff .
lolwat? i love gw and it's a much better game but me is objectively the better rpg since it has c&c in your build (no such thing when you can respec nearly without limitations) and its skillsystem, though shittier, is tied to social, combat and world interaction. no such thing in gw.
I start to think that C&C is overrated in computer rpgs ,guild wars has none but i had much more pleasure, and feel much more freedom, testing characters and party builds collecting elite skills , making armor sets than the fake pseudo choices and consequences you get in mass effect. Most of the praised classic(BG, wizardry, ultima , might and magic, gold box) had no C&C at all yet i still prefer them. I will take a good story and combat system above C&C .
Ideally the best is having both but its ultra rare.
