I will end up eventually playing ToR. its without question.
I however am really not a fan of the star wars franchise. I like elements of it, but it really doesnt do much for me personally.
I will be playing, expecting that the "story pillar" Bioware has been talking up for the last year will be something that will finally change the nature of MMO gaming across the board (although, its not like FFXI didnt already do it, so they need to quit talking it up like its an absolute revelation)
Heres what I expect from ToR. First and foremost the game play mechanics while better than the average MMO are still going to be an MMO equivilent to the queue system from Kotor, which in my honest opinion wasnt that great.
Secondly, the story elements will be alot more vast than people generally expected. However, given the nature of it being an MMO, I suspect that alot of the "end game world story" will prevent someone who perfers to play solo to fully feel in favor of basically requiring leaning on MMO conventions of having to have large groups to do anything of merit.
Lastly, I expect some will end up dissapointed. My best friend is a complete and utter star wars fanboy (though he will never admit it) As well as a role player. I already know full well that he is massively going to be let down. ToR will be big. It may or may not be a wow killer, but its going to have a sizable population. With such, the same cliches that players created in other MMOs they will apply to ToR. Griefers, gear whores, raiding, turning a game into a secondary career, trolling in chat, ect ect ect. I really do not forsee ToR finally being the game that convinces large groups of people to roleplay, and by the same measure I fully expect that roleplayers will be jabbed at in ToR by non role players the same way they have been in every MMO to date, as well as in real life (see LARP and Ren Faire)
All that said, I do sense its going to be big, and popular, and I expect it to mostly deliver on what bioware is promising. I will play it, because it IS going to be the next milestone in the history of MMOs one way or another. I just wish the MMO genera wasnt so slow to evolve.
