The advantage presumably is that a player gets to experience Total Annihilation's gameplay as it was originally released, without any rebalancing. It's interesting historically as the root of its own lineage of RTS games, it's interesting from a nostalgia perspective, and it's a great, if dated, game in its own right; the campaign, music, and narration still hold up nearly thirty years later.

To whoever put it together, thank you.

Isn't this just the ebitengine doing all the work, with someone having used AI to vibe code TA functionality on top of it?
