Aside from kids who order it for their birthday to their aunt... I can't seriously believe that people considering it as the new Halo FPS will have a considerable impact on sales (...
).
You really have to be a blind idiot not to see it (Hellowww !!! Flip the box please...).
Halo Wars is a real challenge because it is the very first console rts (not rts for console like a port of C&C) .
Its inovative controls is a real bet on how the RTS genre can be made accessible to non-rts player.... and as a RTS player, I played the demo for like 5 hours and it is a deal for me ( I can't see C&C on my 360 anymore... brrr..).
The only think I'm worried about (and I'm almost already sure about it) is that it may miss the hardcore-rts audience due to its controls simplification and its orientation on balanced actions.
... it might also be a bit short on the campaign side (opportunity for paid DLC of course... hinhin...) and too focused on multiplayer...
