From what I've read about the gameplay throughout the beta and here, it sounds like the style has moved closer to that of Total Annihilation, one of the best RTS ever IMO. Though Metal Fatigue was high up there also, great game but under-appreciated. But as for the TA style play, by that I mean you have to use your head. If you can survive the early rush (Which really sucked in TA, damn Flashes/Slashers), then the enemy will have to be a tad smarter than amass one unit and rush ala Blizzard games (Though I'll admit, WCIII was a huge improvement over all their previous RTS gmes). I hope that's the case, C&C has always had a place in my heart through thick & thin. I hope this doesn't disappoint.
Another thing I'm curious about is the music. Is it the same metal-techno-esque (Sort of reminds me of KMFDM and MDFMK) music that was used in previous games or did they decide on a new style? In either case, how is the music? Pretty good? C&C music always had a way of pulling you in and setting a good mood. Well, me atleast.
