Well, that's quite a system. Add a map difficulty coefficient, fine, or some kind of bonus, or party strength – but remove the occupied space from the calculation :)
I know how to play, and suspecting that many others can achieve a similar completion time, I will try to surpass their results based on secondary criteria. I will collect more oil than anyone else during this period and prove that I am the best! Isn't that a reason to be interested in the game? Why are you rejecting this?
You're not removing the space from the calculation, but a secondary criterion! And all because you don't know how to take it into account... Look for a way, change your method for this, instead of criticizing others for no reason!
