How would auto-buy work, like how/which upgrades would you determine need to be auto-bought? And what if situation/plans change? Feels like auto-buy isn't meant for this kind of game and it's more for classical incrementals where you are endlessly buying hundreds of simple producers.
Yeah it's definitely not as necessary here, my only thought is after a few prestige having to buy the basic upgrades for each building each time could get a bit tedious. Something like a perk for specific buildings that only buys gold upgrades if they cost < .01-.1% of total gold could help smooth out the post-prestige bits.
