The Old Republic

So last night my brother wanted me and my sister to download and install Star Wars: The Old Republic on our computers so that we can play it with him. We were up all night waiting for it to install, and now that it has, I've slept a few hours but my eyes aren't up for playing yet.
So, what I'm wondering is: how many of you play this game? How good is it?
My siblings are playing it now, and it looks alright, but I'd like some opinions from you lot anyway.
