Heroes VII

The combat AI is idiotic - enemies ignore dangerous opponents, finish off small units, and fall for stacks of a single creature just to get a morale bonus (even undead!), and archers charge into melee.
The auto-battle somehow manages to lose against a "minor opponent."
You're besieging a fortress, and these idiots come out of it for a fair fight. But what's the point?

Isn't that how it always was in every game?
In addition to everyone else who has commented on the game's unfinished state and poor quality, I'd like to add that I was personally killed by the artwork of the creatures in the codex. Releasing in-game art that has already been on the internet for three years, and then forcing you to click on each one separately - that's something else.
