Clean and straight forward gameplay. Some may dislike the balance, but percieved issues are mostly failure to play a suitable strategy for the situation. For example, some classes' armies have an advantage early in the game, but can't stand up in long games. It is up to the player to account for this. Some might find that frustrating, but I think it makes the game more interesting.
Cool game. The races are fairly well balanced. Gameplay is heavily RNG dependant, but there are built-in ways to overcome randomly generated disadvantage or blow randomly generagted advantage, so it's interesting even if the odds don't favor you. Overall, it's not a masterpiece, but it's a good game.
