Once you get deeper you wont even bother with greens. It's blues or better.
Personally I hate the "1 item, 1 slot" inventory. That's the one thing (and multiplayer) that I don't like about TL.
Yeah, I don't like that little things like rings take up the same space as a two handed weapon. They should have a separate pouch just for the small stuff.
I'm somewhere in the 50s, and have been enjoying things for the most part. I am pleasantly surprised at how much there is to this game. The main story is fairly meh, but there's a ton to keep you playing. The pet system is very good, although it'd be nice to have more customization. I don't ever fish or even pay attention to it beyond using it as a mule to be honest. I'd like to see them evolve the idea and have it so you can have your pet buy potions.
The lack of co-op is still a big miss for me. The other issue, is when there's tons of drops in a small area, its a pain to sift through it to find what you want. I'm indifferent to the visual style. Its appealing, but after playing this, I do think Diablo III having a similar one is going to be a letdown since for me personally. The MMO should prove interesting depending on how similar it is. I have been missing a game like this.
Lastly, I'm actually surprised they didn't port this to consoles. Its got more character than the last ones I played on consoles (Baldur's Gate and Everquest which were snorefests, literally I fell asleep playing the one with a friend). I think it would actually translate well, and they'd do well financially. I know its blasphemous, but hey, I'd like them to do well enough to keep making games and improving things.
