Some really good improvements have been made on the original game as well some questionable changes. Improved AI, diplomacy, building queue & some new spells are among some good changes. It seems that some other changes were made for the sake of making changes without really adding anything meaningful. It would have been nice to have added some sort of multiplayer for human against human play, even if only over LAN. The addition of an extremely large world & the ability to play against all the wizards at once is very interesting. However, for some reason, enemy wizards randomly retire, quit, go missing, ect with neutrals taking control of their cities even early in the game, which makes one wonder why they would even be included in the game in the first place if you are not actually ever going to play against them. It would make sense if they were defeated by another wizard or wandering monsters or perhaps the victim of rebellion, but for an AI opponent to just get up, walk away & say I don't wanna play no more makes no sense at all. I even turned off random events to try to keep this from happening but wizards just quit the game randomly regardless.
The game play is really good. There are still quite a few crashes. Unacceptable that experience cap is set half way through level 4. Maximum character level & have not finished 3/4 of early access content. For this reason, I do not recommend spending $60 on early access.
