Ummm... I played both Overlord 1 and 2 and loved them both. Yes, I got both of them for the PC and I still loved them. "Being a dick isn't as fun when you're supposed to be a dick" not being fun? Ummm... Yes, you are supposed to be evil, but really Yahtzee there really isn't a moral choice system here, at least not in the conventional sense. It essentially boils down to Enslave or Kill everyone, and either one is evil. And Yahtzee, both games were set in a typical fantasy world that eerily resembled something that Peter Molyneux would come up with because rather than having you trying to save the world from an ultimate evil, you are trying to take over the world. And as for controlling your minions, I found the controls to be pretty intuitive because, as you may or may not have noticed, the minions will continue going in the direction that you have the mouse pointed at (like, oh say, how you would be moving yourself with an analog stick if you were playing this game on the 360), and while yes, it did take me a bit to grasp that concept while playing through the first game (after the two sweeping tutorials I started experimenting with the minion sweep mechanic and figured it out in about 1 minute). And as for the lack of personality for each minion, well, yahtzee, you seem to be forgetting that each minion is defined by its function, that is, they minions personality's are derived from what they DO: i.e. kill people and knock things over. The minions' collective personality is perfectly suited to what they do: your minions want to go out to battle at your command, they WANT to destroy things, they WANT to kill people (whereas in other, more traditional RTS's, the game's storyline makes it clear that your units are there only because they have to be). As for the mistresses, Yahtzee, you clearly didn't get far enough to enjoy the benefits. 1. if you buy enough Netherworld tower upgrades from a particular mistress, you'll get a PG-13 sex scene with the minions trying to peek in on you while the camera bounces around, and 2. during the final battle, depending on what mistress you have chosen to be your first mistress, a different minion type will be supplied with its mount (browns = wolves, reds = salamanders, and greens = spiders). And as for the whole "stealing its core mechanic from Pikmin" thing, well, yes, Overlord kinda does just that, BUT what it does do differently is that Overlord provides a much more plausible context for why this horde of little... things is following you around.
Finally, to address that issue of "sweeping your minions through a maze with a time-limit", well, yes I think I know what section you are talking about Yahtzee, and I can assure you, that the spider-temple elevator is the ONLY place in the game where you'll see something as hard as that, and I got through that after about 10 minutes of solid effort on my part. And again, Yahtzee, aren't you always the first to complain when the challenge of a game "is thrown out the window without a a goodbye or tip of the hat"?
