I am willing to tentatively recommend this game. If you buy, you need to remember that you are purchasing early access to an unfinished product. You cannot expect it to be free of glitches. TaleWorlds has been great about pushing out patches and fixes. However, please note that the only thing that currently works in this game is open combat between two armies. Sieging is broken, kingdom management is broken, and nearly every single quest in the game is either unfinished or broken. Also, entire skill trees, like "Trade" are broken.
You cannot gain "Trade" skill no matter what you do. These things don't matter to most people because the open battles are what made this franchise famous. I just want you to be aware.

With the negatives out of the way, let me say that this game has limitless potential. I mean LIMITLESS. Even without any coherent story or questline of any kind, you can still get a hundred hours out of pledging yourself to a lord and then riding around and fighting. The world is amazingly well built, beautiful, and enormous. The combat is fantastic fun. However, TaleWorlds needs to deliver on the story and quests if they are going to save this game from oblivion because the world feels utterly hollow. Great graphics and great mechanics are not enough to make a great game. You need a context and reason for the combat. You also need depth to the world. Right now, all of the towns, cities, and castles feel vacant because although they are full of NPCs the NPCs are just wandering around aimlessly. The quests offered to you at random by village NPCs are pulled from a grab bag of the same six quests.

Let me offer an example of the hollowness I am talking about. When you get married, there are no unique interactions or conversations with your wife or husband after your marriage. You have the same stock interaction options you have with any other noble. The only difference is that when you leave the interaction, the husband/wife says goodbye husband/wife. So what interactions can you have with any other noble? Basically just offering them presents in a trade window. Your spouse will randomly get pregnant and bear you children but don't try to talk to them about those children.

The bottom line is this: if you get this game, know you are getting it for the combat and gambling that when the full game is released, TaleWorlds will patch in enough quests, enough story content, and enough voiced dialogue to fill the aching void at the center of this game. If they do, it will be one of the greatest video games ever made. If they don't, you are paying Triple A prices for what is only a medieval battle simulator.
