I got really into C&C with Tiberian Sun and Red Alert 2 was a big change but I fell in love with it for the same reasons you mentioned. It's been the most disappointing part of seeing them open source all the old games. That this amazing game AND Tiberian Sun won't be part of it because they lost the code.

The "we made units this way because it's fun" philosophy is sorely missed. Every game feels like it goes through a tuning phase just for esports. Even if the game isn't out yet.
