I think they are unlikely to sell it... unless another big game developer offers a lot of money...
What they need to do is give it to a passionate developer within their umbrella & just let them make a good C&C without corporate EA interference. No paid DLC, “free to play” horse shit, etc.
It’s a fairly niche market RTS games, nowadays, (with the exception of Korean esports)
So I wouldn’t say there is a large profit margin. I don’t imagine it’s worth investing large sums of money in, like in Battlefield for example.
I think the best we can hope for at this stage is a Red Alert 2 Remastered, Similar to the Age of Empires game.
Although they could use the IP to make a cool profitable games, for example combining something like Battlefield 2142 & Tiberian Sun together. But yeah, nah they’d rather make forgettable mobile games instead. ?
