Ah Mr Yahtzee, I see we once again have a case of you WANTING to hate a game. Let me point out your errors.
1. Overlord 2 is a Console title first, PC title second. You got the wrong system.
2. Overlord 2 is meant to be cheesey, linear, and comical. Just like the first one, which was a hit by the way. It's meant to be a satire game, not something you take serious, which you did for some really weird reason.
3. I'm not sure how you found the entire game boring. It's quite fun and humerous. The point of collecting the mistresses is to complete your stereotypical evil entourage. It's not meant to be a serious evil simulator, it's meant to be poking fun at itself.
4. If your minions didn't run over most everything like a steam roller you wouldn't be playing an evil overlord now would you? You'd be playing an evil pansy.
5. The idea behind getting back your minions has nothing at all to do with being attached to them like Mr Molyenx and his nameless hero's, but rather is a response to a complaint about the first game. In the first game, you could equip your goblins with different armor, weapons and items depending on what you raided. However, when they died, that was it. Lost all that hard work making them strong. Now you can raise them, as your minions level, and thus you'd likely want to keep them since it makes the horde stronger. You'd probably have noticed most of this if you hadn't been trying to hate the game.
Basically a lot of this review sounds like bullshit. Plain and simple. If you choose to play a console game on the PC, then expect to deal with porting issues. But the rest of it sounds like complete rubbish. Pull your head out of your arse Yahtzee, and review the game properly.
