Just played the Kingdoms of Amalur demo. It made me a sad panda. It has so much potential and could be very fun, but it's buggy as shit. Even more than Bethesda games are on release.
Other than the bugs, combat is quite frustrating. Also, turn on post processing and the framerate becomes terrible, even though the graphics aren't really amazing. Turn it off and the game looks like just like World of Warcraft.
And since it's releasing in about 10 days, I don't think they're going to be able to fix much.
I just read that the build EA used to make the demo was 3 months older than the final build. The developer 38 Studios says the release version is far better. I hope it is.
