I have been playing WoW since Beta, And my gametime just ran up, Not sure if I should re-new, Or try out this game?

Is it similiar too WoW? Better?

Its personal preference.. There is a lot of things that I don't really like about swtor but there are things it can offer that other mmos can't.. If you are into lore/story I would recommend swtor.. If your looking for a refined game you probably shouldn't get swtor

great answer
You'll have to try it out to find out if it suits you

What they said. Watching a stream would give you a bit of an idea.

IMO: You're not going to be seeing new content in WoW until MoP. So I feel it's worth giving swtor a go instead.

i like it! i've been playing wow on and off for so long and it just seems to be getting worse as the years pass, imo. i found the change of pace yet familiar ui of swtor really fun and refreshing
