Summary: Don't buy it if you expect Dungeon Keeper. In fact, just don't buy it. The gameplay is extremely tedious, and it's just a sad waste of time. It feels and looks like a lot of effort went into its production, but it doesn't matter because the gameplay isn't cohesive, and it's not fun at all. I have a serious feeling that the "10" reviews are friends and family of the developers...
Summary: Complete rubbish. Nice graphics and voice acting, but that's all. Stupid campaign that's just a linear tutorial, no option to avoid it, no sandbox mode. Unless you're a complete moron you'll be bored silly within minutes. A cut-down version of Dungeon Keeper. Very buggy and crashes often. Stupid over-powered boss fights as a substitute for mission design.
Summary: A mix between Dungeon Keeper and Evil Genius, with none of the features that made them games classic. So many things need to be said about this game. Firstly, the core idea of the game and its humour are interesting, but really fail to entertain. Textures are fairly tacky, and the voice acting is fairly bad, but that isn't what makes this game awful. The core mechanics seem to defy the genre of the game.
Summary: This game is absolute disappointment and disgrace for Dungeon Keeper legacy. While being graphically appealing it lacks so much in gameplay department that it made it unplayable to me. Dialogues are stupid and main two characters are nothing but annoying. Combat system are imbalanced making 90% of units totally useless (all except melee dps and healers). Heroes spawning all over you dungeon makes usage of traps and complicated dungeon layouts absolutely pointless.
Summary: This is a great game by itself. I give it an 8 because I have a lot of fun playing it. Impire has launched with basically a Quasi-Beta status. Lots of random bugs and game play mechanics that need to be balanced. A lot of people compare it to Dungeon Keeper and Dawn of War. It isn't very much like DoW except for the "squads". Squads are a must too, because if you just have units (not in a squad) they get slaughtered by squads of heroes.
Summary: This game is not a dungeon base building sim, it is a micromanagement-intensive RTS. The gameplay's basic routine is: 1. send units exploring to complete quests. 2. teleport units to fend off invading heroes. 3. send units to kitchens to refill hunger bar. 4. repeat, with occasional digressions for overworld missions, construction, unit training, and upgrades. The hero incursions and manual unit feeding don't add any fun to the game and just distract from exploring.
Summary: I have actually played the game and and after seeing the delusional reviews here, I felt compelled to chime in. (8.3? Really?) The atmosphere in the game is fine, and the humor, while a bit simple, is also fine. The real problem is the game-play. It isn't fun. In fact, it can be rather tedious. Basically the game consists of 5 parts. Building your dungeon, defending your dungeon from heroes, adventuring, raiding, and maintenance. No, it is not as exciting as it sounds.
Summary: One of the most atmospheric dungeon-based games I played, the graphic style, the mood, the neat sound effects all add nicely :-) You can, for example, zoom the 3d-view out until you get a top-down map like view with different symbols for your rooms, if you hover the mouse over these room symbols a new window suddenly apears and shows whats going on in these rooms.
Summary: Its been described as Dungeon Keeper meets Dawn of War 2 and they seem like accurate reference points. Don't expect a straight modern era version of DK, its not that and it hasn't pretended to be. The gameplay is pretty good, and it runs well but for me, I found the level of micromanagement needed for your troops was a bit irritating, it could also be a little easier/quicker to navigate around the map. Voice acting and dialogue seem above average.
