This game was made as an RTS which means it is not a first person shooter! That is fair warning. As RTS games go this is a great one for a console and hopefully other games follow this example. However, if your a huge RTS fan on the PC then this game may not give you the same feeling. It is not as in depth as PC RTS games are! But just like other Halo games this one shines more on multiplayer. Once you go through campaign your pretty much done with that. The mutiplayer adds to its replay value, so if you dont have Xbox Live then this is diffently a rentel for you.
You should already know this is an RTS game, but seems some don't. I have never played an RTS game before, so here goes: I was not very impressed at all with this game. Can only build on specific locations, limits on how many troups, vehicles and aircraft you can have at 1 time. I realize this is probably for the benefit of the graphics card, but it is so tiring to try to build another tank when it tells me I'm at my limit, which I believe is a limit on vehicles, so be careful which ones you build. Overall I found the game fun, but very short. Remember, never played one of these before, so started on easy, which was a joke, as it took me just a few hours to finish, next tried normal which gave some challenges, but nothing more exciting. I'd suggest renting this game first before buying as this isn't something I'd consider owning... too short, not enough options, just got boring, fell short of expectations
