Looks like it’s not just Tempest Rising trying to fill the retro ‘Command & Conquer and Red Alert like’ void. There’s an indie game project called Global Conflagration that looks rather promising too! From the outside I’d say it probably has more of a C&C Generals feel to it with a bit of Red Alert thrown in too. They recently did a public demo period leading to lots of feedback that will keep them busy for a while but apparently they plan to do an early access release later this year. Dunno about that name lol, but it looks pretty cool!
