You know, your post contains 2 different main points: AI usage and new RTS game concept. Unfortunately, you refuse to elaborate more on the latter which is a more useful discussion IMO. But fine, I'll play along.
do people generally accept AI-coded games? or are they often ignored/disregarded as slop regardless of the merits?
TBH, it's not easy to tell if a game is AI-coded or not. However, some ai-coded games have clear giveaways on being ai-coded. If people see those giveaways, get ready for backlashes.
People consider AI coded games and games using gen AI artworks as lazy work since the "devs" behind those games don't spend any effort in the creation process. Maybe those games do have merits but the AI stains are enough to keep people away.
Now allow me to ask you this question: you have lifelong passion for videogames, so why don't you use that passion to learn coding or at least learn to use an engine?
