The early access is fairly buggy. I've had save games corrupt and many other bugs BUT I am enjoying it. If you do purchase the early access version keep in mind you are alpha/beta testing the game. The game is in no way complete and missing lots of features. As for the skills system, it is fairly similar to other M&M games albeit a slight bit simpler. Things are changing though so its hard to say what will be finalized. I follow the game via the developer website/forums.http://might-and-magic.ubi.com/mightandmagicx-legacy/en-us/home/index.aspx
