May I remind everyone that Halo Wars was originally to be released for PC and Not Xbox; due to the complicated controls they didn't know how to manage at the time. If you look at the beta play tests, they use mouse and key.
Edit; this is from my memory, and I'm not fully good with memory. But I do remember them saying that it would be released for PC if the control issue was not resolved; which we all know the outcome today.
Fact is with the modding community and such, halo wars would quickly become one hell of a great game due to it's art style. I'd love to replace some of the characters with head-crabs from half-life or something, it would be awesome!
The thing you guys arn't quite looking at is the potential it would have. You're looking at it ( from what I read ) as it is, but in reality because PC is so much more Open, it would be even better because of the lack on restrictions. This game hands down would end up being amazing on PC.
And are we forgetting the story line this delivers? For once we have a Halo Game that doesn't have master chief in it at all, aside from the one mission that has the pillar of Autumn in the cutscene holograph for a few seconds before they warp out.
I think this game was well made in terms of story, and general gameplay. Could of been better in terms of game mechanics but I like it.
