Back when Peter Molyneux made games ... with Bullfrog, there was an ace tower defence game called Dungeon Keeper. I reviewed it, must have been in 1996. It was jolly good back then.
Now, EA owns Bullfrog and EA is into mobile gaming... and EA owns Mythic too. And tower defence games are a hugely popular genre on things like the iPad. BINGO! Let's 'reboot' the game.
The game, where you play a godlike devillike Dungeon Keeper who must make it minions expand his dungeons while ensuring that your dungeons are not attacked and destroyed will also be out for iPhone and Android devices.
