Ensemble has told the hardcore gamers to go suck it...and suck it I will, because this game is amazing.
Gameplay
Literally perfect, minus a few minor gripes. For one, the controls are tough to get used to, though they are very powerful once you get a hold on them. While there isn't that much depth to the gameplay on the standard of RTS games, that is NOT a bad thing at all. The simplification of the core RTS design is going to attract a ton of new players to the genre, and I seriously hope this isn't the last Halo Wars, because I have not seen a better balanced RTS since Warcraft III.
Graphics
Good enough, enough said.
Sound
Ditto Graphics.
Multiplayer
Dead on perfect. Ensemble has nailed multiplayer as well as Bungie had with Halo 3. The matchmaking system shines, and honestly, this game is as good or better than ANY multiplayer RTS on the PC in multiplayer. It may be too simple in single player, but that simplicity turns out to be an asset in multiplayer.
Way to go Ensemble, its a shame to see you guys go. I seriously hope Microsoft has the good sense to continue the Halo Wars license, because this is a great game.
