I try not to buy books unless I can get them used at a local bookstore, because I don't have money to pay for shipping off of Amazon. So I usually just end up buying the next book in whatever series I'm reading when I find it, but I never finish anything.
I could see Mat being dislikable early. Any scene with Elayne and him is sort of annoying. He develops a lot though.
I finished book 10 of WoT. I think you read it more for the experience than to find out what happened. Like someone else said it's influential. I don't really want it to end. OP there is one prequel if you haven't read it yet and a "World of WoT" type book coming out soon.
ASOIAF I'm up to date with. I enjoy it, but I don't watch the show and avoiding spoilers with is frustrating. It's kind of ruined the experience at times. From what I gather the show for next year got pushed back, so the book should be out before the show starts again.
I read Gardens of the Moon a while back. I really like this series, but I never have any luck finding these books anywhere used. At first I was conflicted about how much stuff he leaves out (I read it between a couple of Jordan books) but the book just went so fast for me because of it. Plus the way that he tied all the characters different plot lines together was admirable. The history, magic and pantheon system that he's developed really drives the plot for me.
I'm currently reading Hobb, I'm on Assassin's Quest right now. It's weird reading a fantasy that focuses so much on the disabilities of the protagonist. She has an interesting focus for high fantasy, which makes it kind of a breath of fresh air even with limited world-building so far. I gather that the other story lines in this universe focus more on the world building.
I've enjoyed the Discworld books that I've read. I'd like to read them between heavier books, but they're so short and sort of hard to find. I don't have a particular desire to read the entire storylines though.
The Black Company is probably my favorite series. I'm not sure I could have gotten into high fantasy without it. I can't wait for the next two.
