Youtuber, Ianbus put out a video a few months ago looking at the games seeking to supplant Total Annihilation.
"Total Annihilation and its successor, Supreme Commander launched a new kind of RTS game, one characterised by gigantic unit counts, hundreds of unit types, a novel approach to “macro” and devastating weaponry, with projectiles modelled in real-time and the very terrain changing as a result of the endless battle between machines.Many years since the dust has settled… the conflict to become the “spiritual successor” to these legendary titles is heating up (in a good way). I’ll take you through the story so far and showcase some of the best existing and upcoming titles to scratch that TA/SupComm itch."
