I hate to play devil's advocate, since i kinda hate Bioware, but
SWTOR uses the Hero engine, not the WoW engine, not sure what you think engine means
Resizeable horizontal and vertical toolbars of abilities isn't exactly a patented Blizzard invention
MMOs require maintenance, customer service, and ongoing development, which isn't usually covered for their lifespan of years by initial box sales
Unless you're talking about people talking dirty in General chat, it's no "Darker" or more "Mature" than the KOTOR games, maybe even less so
I'm not convinced you actually played any storylines, since none of them are about you being redeemed or being the "Chosen one"
There are group quests, 2-man heroics, 4-man flashpoints, 8-16 person warzones and operations, not to mention guilds, player crafting, and RP, how is it you avoided all player interaction?
Yes, Bioware made a mockery of Revan and shat on Obsidian's characters
I don't believe you know what grinding actually is
ultimately i think you dislike it because it's an MMO and not KOTOR 3
i'd rather have the KOTOR 3 as well
