There are a few nice ideas, but ultimately it falls down, sadly. Nice graphics, simple enough game play... But there are real problems with it. It's too short (A mere ten levels) has no proper troop commands or formations, and is far too easy for most of its length.
It can't honestly be described as D&D either, as it bears no relation whatsoever to either the game or any of the many worlds created for the game.
It's only noteworthy achievement is being one of very few fantasy RTS games, but it's not a patch on WarCraft 2, let alone 3 - and with Warhammer Fantasy on the horizon, it's about to be eclipsed even more.
The squad cap is absurdly low, and the number of different unit types you can practically field is four - of which one will be a Rogue, who has limited combat use only. There are also many buildings you will never build because they have no real point in the game, and your building grid is incredibly limited.
Where they should be trying to create a fantasy version of the Total War games, they settled for a superb looking game with gameplay that would have been state of the art ten years ago.
I finished 9 levels, realised I was bored out of my skull, and didn't even bother starting the last.
I guess my advice would be - play it by all means, but don't expect too much.
