The demo is a terrible representation of the game, IMO. I got it off impulse. The campaign (at least the earlier missions) are much easier, and it scales up. There are a few singleplayer non-campaign missions, but no sandbox. Also no co-op multiplayer vs. the AI. I so want these features.
That, and the hero and monster AI absolutely suck. A non-programer like me could have written better AI. This was clearly a low-budget, low quality game by people who didn't play the original Majesty. Agree that it's much more of an RTS. But fix the AI, and add sandbox and co-op multiplayer, and this is a great game. Apparently Paradox is making the Russian developers scramble though, so I wouldn't be surprised if these features do get added. Hard to wait though.
