Sometimes I have 'max' selected for upgrading generators and it either upgrades far less or a little more than it says. It still consumes all the resources.
I also feel the cube size, click radius, and click speed prestige upgrades are pretty pointless, as they only raise the starting level without absorbing the cost - I can attain what these upgrades give me just a few seconds into the run.
For the generators, I believed this issue was fixed in v2.61 however I've since reworked the max-buy calculation to be better. Hopefully in the next update this is no longer an issue if it's still present!
For the upgrades, I've thought that same but haven't decided what I'd like to do (if anything) regarding this. The talents for these is more so meant as a means of not needing to keep upgrading them, seeing as they have a cap. Where as increases to damage and other similar stats you'd want to scale forever.
Click speed is meant to be maxed out relatively early simply because people will just use an auto-clicker so I may as well add it to the game. We don't need to be getting RSI!
Cube size and cursor radius I've been wondering about moving them away from upgrades and being instead tied to something else, maybe only as talents or instead tied to stage level but would require me to re-balance everything. I'd love to know what people think, if that'd be any better or instead keep the current system and just have me adjust costs.
Some incrementals simply have it so the prestige tree upgrade not only upgrades the item but resets the cost as well. So, if you have 5/10 levels on the talent tree, you'd start the run with 5 levels, but the initial cost is the same as if you were on the first level, and continues to scale accordingly.
Just an idea if you haven't considered it yet. There are other valid solutions to this problem, as you mentioned, of course.
