Why wouldn't people compare this to WoW? It's the biggest video game in the world, and it's the same (comparable) genre. People NOT comparing it to WoW would be more of a surprise.
Also, I don't see how SWTOR is WoW in anyway. From what I understand, SWTOR is heavily focused on the single player story and campaigns right? That's not very WoW.
Care to explain how you came to this conclusion?
As for the WOW comments, it's only natural that a lot of post WOW MMO gamer's only have WOW as their first MMO. WOW got most of it's inspiration from the leading MMO of the day which was EQ. They bough the questing you see today in most MMO to the MMO world and they also bought the UI's you see in most MMO''s today. EQ2 had problems and many EQ players moved over to WOW and also from other MMO's.
Right place right time was Blizzards secret even though WOW popularity didn't happen over night.
EQ was blizzards inspiration and hiring players from top EQ guilds.
TESO has things common with WOW as does nearly every other post WOW MMO, that's a fact. TESO is a themepark MMO just like WOW which is a themepark even though the actual world is more open that TESO.
