Playing beta 3-b I find it sooooo much better than previous builds, dispite it crashing after a few turns. But combat is in, spells are fun, questis are interesting, diplomacy, npcs; it is looking like a game.
My only really critism right now is how laggy the game feels. I have a quad core, yet when I click a button to move, or to cast a spell, or to build a building, or what have you, it feels like a 1 second delay. That one second delay though small and somewhat easy to just roll your eyes at, breaks the flow of the game. I do actions, and that delay makes me think I can't do a certain action, or that the spell I tried to cast didn't work.
So just like one poster said, in order to give good feedback, I need to focus on the gameplay and not these strange bugs or lag times.
Besides that, the game is looking better and better.
