Current situation in game is such that there is 160 mfg and 140 retail businesses. Basically its impossible to sell all manufactured cars even without the fact that markets shrank. MFG produces 84 a day and RTL can sell only 60 a day.
I dont know how markets grow and shrink, but for example if they grow with retail businesses and not just new players than this is double trouble.
Basically players depend on what type of business will new players open.
Idea: currently if you have max number of business for your bxp you cannot close one and open new one since closed one also counts toward business number. Basically old players completely depend on new players decisions (and new players rarely know mechanics of game). It could be beneficial if we are allowed to close a business (or 2) and start new one, with max number of businesses being counted only for open businesses. Then older players could for example close some mfg and open new retailer thus impacting balance of game mechanics on their own.
If new players keep opening mfg businesses instead of retail, game could soon become unplayable.
