The suggestion here is to introduce more rentable shops, especially stalls, food vans, news stands etc in government cities.
Shops specifically for new players that are rentable as well.
Also, to go into the config for areashop and introduce a maximum rent time to somewhere between 4-6 months. What this means is the player has to come back to rent the plot again and cannot indefinitely rent cheap plots. To anyone who is against this, bear in mind this would not stop you unrenting and re-renting to extend your rent. What it does is encourage server footfall.
