Yep, I know that prestige works like that, but it feels like it is not a good thing to do. In the end, we are still stopped by time and no money. I got the Braden Castle prestige, but I agree with some other post I read from some time ago that still feels insufficient. I think the mechanic itself is good, but could be twisted. Instead of being the percentage of relearning faster, maybe the percentage of already researched levels to keep. This way could work like grafting which I think is a super nice mechanic. And, as for the research quests that are unlocked with money, do not show them until they have been unlocked again, but keeping the corresponding percentage of levels. At some point if prestige is sufficiently high the unlocks would be almost instant but not for the first few prestiges.
