*OPINION*
I agree with @Cap
But also there has to be a balance, its not about one group of people. Its about everyone. Don't segregate the Old from the New people.
New players need some sort of grace period to experience the server without being ran down in an instant. Not sure how this would be installed.
I believe when the runs were all Nerf'd and changed, along with the zones. The server began to struggle because the limitations on how we make money aren't worth while. A lot of people will not touch any of the basic Drug runs or the Wood runs etc.
The prices are fine in my opinion. Just do some runs? Canny because you either get destroyed by Poseidon/ Police depending on the run and then the other runs are worth pennies. Could even just change the locations of the runs? Different timed runs could make it more beneficial for some products even if the price of the product isn't changed.
Poseidon probably need more of a goal than just fighting people also. Id like to see a different faction involved but that could just be because I wasn't around during UNMC.
May be a new or type of uniform like red cross sort of thing that we could all recognise straight away as new players so we could leave them be sort of thing. and maybe when they reach a certain Cash level they can no longer buy this uniform just a thought
