Hmm, I wonder how you'd select units or point them to a specific location?
"alpha squad get to point echo"? i dunno.
it's an interesting concept, but i can't really imagine it being a valid replacement for more traditional control methods.
with an extension of what xessive said above, how do you scroll around the map, how do you group units, how do you set rally locations? with the quick succession of commands you have to input using both keyboard and mouse in rts games, i think it would get pretty confusing, pretty quickly. the only way i can see this working, is if the gmae has a relatively limited level of control, or if a lot of stuff is handled autonomously.
