I don’t think there needs to be an increase really. The other day I cooked for 24 mins and made 30k. That’s a 20k profit in less than an hour. Increasing the value would just make it even more profitable and it would not be a good balance for the economy really.
I think a better suggestion would be to make slight adjustments to the boots the drugs gives. Maybe depending on the tier of drug, you get different durations or something along those lines. I don’t think increasing the value by x10 is ideal at all.
Increasing production time also is not a good idea as well, there are a lot of solo Crims who have to try to cook in labs when larger gangs are not active in them and there already hard on its own. Increasing the time would just make it more difficult/impossible for solo Crims to cook.
