i think its a good game and there is alot of fun to be have ,here are some pros and cons
Pros:
-Cutscenes are Awesome and will make you feel like a bad ass
-smooth gameplay that is made only for the xbox 360 meaning that it was not just another port like the C&C series
-Whole array of casual and elite units from the halo series to take control of e.g. from the smallest grunt to the colossal scarab
-Story is intresting and innotive
Cons:
-multiplayer matches sometimes are kind of slow to start up and deploy some more elite units meaning all your really using are weak and common units
-nOObs on halo wars, most people on halo wars are fun and fair playing however there are a small amount who use all resources to warthog rush you and it gets annoying FAST
-Not alot of replayability
