Way's to play Overlord.
The Goody-good-good-way. (Boring)
Well here, you complete the game without killing ANY friendly's.
This is kinda boring, all you get to do is help little stupid people, give em food, help out elves, and just be damn nice all the time...
Ok I must admit, its good to play it like this the first time, you end up with some cool 'non-corrupted' magic, and a clean pretty 'Dark tower'. but thats it. People like you and that's it. Oh well...
Now, the way you should play it! 100% corrupted!!
The OMG-how-nasty-evil-can-you-get-way (LOLOL So much fun lol)
Oh yeah, more like it.
This way, you get to do al the things an evil ruler should do, smite farmers, destroy the elves, steal-kill all you can, and obtain some AWSOME magic skills that will kill almost anything that walks on this planet, kidnap you some servants and be a jerk allround.
Compared to the good way, the game is more fun like this, you look evil, people fear you, and you get to play a good looking badass asshole... If only we could do that in real life
