War of the Overworld is basically Dungeon Keeper 3 (except the people who originally made it stopped at 2)
Personally, I loved the Dungeon Keeper series and was sad to see it die. However, I am now very heartened by the Beta of WOTO. It's basically Dungeon Keeper, only so much better. There are about a dozen room types, which I have yet to get to grasp with, as well as an impressive selection of spells that do everything from reveal parts of the map to freezing the ground. What I also love is the voice acting is very similar to Dungeon Keeper. The guy who does the Keeper sounds appropriately evil and the heroes sound equally pius, making it so much more satisfying when you kill them.. =)
However, the game is still a Beta. There is a tutorial, which explains the basics (there really needs to be an advanced tutorial as well) also, I found it hard to find the flashing tiles on some of the tutorial actions. Perhaps if you centered the screen over the tiles as the event triggers, this would be easier.
There are only 2 maps, however, there is a sandbox mode, which I look forward to exploring. Unfortunately, it crashed at the climax of my first game, however, that may be due to my OS.
Anyway, as long as the developers get this thing to full version, it will be freaking awesome. Given that all of the room design seems to be done (although I have yet to fully observe what all the creatures do and thier various states) making the maps should be pretty easy.
Oh, there is one thing that distinguishes it from Dungeon Keeper, there is no hilarious CG cutscene at the beginning.
I would like to vote for one, if possible.. =)
I would give it an 8/10 and it's only a Beta.. I can't wait for the full version.
