Yes, I want to know more about those games and their specified characteristic. As Kitzler, I'm interested.
As for dark messiah, watch a youtube video.
About APB, i haven't played it but the customization as shown in a vid sure looked neat.
About world size...the biggest map in this is from Darkfall and the yellowish thing is from Oblivion:

What Lotro definitely did right, was the environments even though otherwise the game was pretty generic.
