I have some suggestions for rule / category changes:
Rule: Need to specify any premium upgrades / research / building / cash injection used/active. Reason: Reference mostly, so we can see exactly what someone used to beat that map. Maybe a strategy is only viable with that building or with a minimum research threshold and it would be nice to know it.
Rule: Specify that all tracks need to be played from round 1 to 50 to prevent people fast tracking. Reason: It reduces the time it takes for maps without any good reason. Either that or allow it for everything for consistency, though I'm personally against that.
Category: Split PC and mobile Reason: They have different maps (mobile has two less than pc) and mobile is faster meaning an optimized mobile run cannot me beat on pc, having them compete if unfair.
Category: Split any% into beginner, intermediate, advanced, expert and extreme. Reason: Although I can understand not including extreme as it requires you to pay to enter unlike the other difficulties excluding expert seems arbitrary, is there a reason why it is excluded from any% currently? Another reason to split is that a current any% run takes too long, the only one currently available is 3h 40m and uses fast track for all tracks (and once again, excludes expert). Splitting the any% runs on map difficulty might make it more viable to run as optimized runs should only take between one and two hours per difficulty (without fasttrack).
