They´ll need more than a remaster to make C&C1 interesting to play today.
They would have say a reboot with new design, I would have had some hype but even if I slept hundred of hundred of hours on the original when I was 14, today the game mechanism and design is just out of date.
At least they'll have squishing. I don't think RTSes ever really do that much, strangely enough. If it happens in CoH, it's almost a bug.
