They should really have put some more work into the UI art. Except for the fonts the whole UI looks blurry, like they took that stuff straight out of the PS3 version and just upscaled it instead of using a native 1080p UI. The inventory icons even have something that looks like JPEG artifacts in them. Makes it look quite cheap.
Anyway the game is a blast. Onto act 5 now.
Personally, I absolutely hate the fonts in D3.
They are not stylized in the least, and make the whole UI feel like a cheap MMO patcher window.
