I played this for a while to give it a fair chance, even though I didn't like the look of it.
My summary is: If you're looking for a mobile-style "building strategy" game (think Simpsons Tapped Out) then this is probably a good choice for you. If you're looking for a class Dungeon Keeper style game, this most probably is not for you.
It does have some of the Dungeon Keeper humour, creatures and ideologies, but otherwise it's not really much of a Dungeon Keeper game.
There are microtransactions for all the usual tricks - things to buy, speed up this activity that you would otherwise have to wait hours for, etc.
There are time based things that you can do in the game that you will be prompted to return the playing for - such as slapping your imps to get a 2x efficiency bonus.
So yeah, it's a bit of a shame that this is how Dungeon Keeper gets renewed, but if you do like mobile games it is worth playing.
