Not to add fuel to the fire, Frogboy posted back in the fall of last year that he had some "revolutionary" ideas to make the single player more than just a set of combats against AIs.
The tourney mode was a part of this but, I have a feeling that there was something cut out. Prior interviews with developers from GPG and Stardock also made mention about things like using favor to hinder opponent Demigods, permanent/temorary Single Player advantages for their demigod, or Permanent Demigod specific Gear to pimp them out.
I like the game. I enjoy the Single Player against the AI. I like the favor system. When Multiplayer works, it's pretty nice. Heck I love winning from the underdog position of a 3 on 1 via Pantheon.
I do feel that a basic tutorial wouldn't have been amiss. Heck, I was in the beta for 7 months before someone told me how to buy Favor items.
I'd recommend this game to my friends who enjoy action/tactical RPGs but, I'd caution them to not expect a huge single player experience.
