Way more in depth with everything. I've only played the alpha/beta version because I backed it on Kickstarter and it doesn't even have all the new stuff in it but it's like the first game on steroids. There is several different races now but the alpha/beta doesn't have them all, you can pick your race, back ground story, etc. now and it affects the story, quests, and how characters (including your own party) interacst with you. Some races are well respected, some aren't, some are feared, etc. There is actually an Undead race I want to play as but it's not in the game yet.
Again, this is the alpha/beta version with just a couple areas, races, spells, etc. Not sure when the full game comes out.
