After reading some of your posts i think you're confused about a few things. First of all you seem to be comparing PWO to games like WoW, which is a very bad comparison for several reasons. You want to implement the token store in game because you say it will increase revenue. To be honest as long as PWO gets enough money to pay for the server, which they always have, then it doesn't really matter if they get a lot of money.
PWO can't hire developers, they cannot legally pay ANY of the staff members. Every one of the staff members is a volunteer. This is a fan made game, the token store is already on the thin line between legal and illegal as it is. Adding the token store in game will literally have no benefits to PWO, the only benefit would be catering to the laziness of the players, instead of simply going to the PDex to do donations and whatnot. The extra money gained from an in-game token store would be useless because as far as i know, PWO can't do anything with that money other than put it towards server cost, and they haven't had any issues keeping it up.
PWO is nothing like WoW, they exist to make money, PWO exists for fun.
