Here is a little example : you buy your first extra house slot, it will cost you 25 mif you buy your second extra slot, it will cost 50 m and for the third you would pay let's say 100 mso every time you buy an extra house slot, it's get more expensive.It's just an example, we can discuss the prices.
1- it's a nice improvement to the new house system2- A great way to spend money as arran wanted since people who buys it will not regret it at all.3- people who wish to make houses a source of income will find it verry useful.But my question is: What happens to the people with donator level? Since they paid real money and your suggestion is one of the perks they have, will it get removed or replaced with something els?
