Hello,
A lot of servers (and games) are remaining competitive by the introduction of additional funding via micro-transactions. A lot of game servers, including SA:MP servers, Garry's Mod servers, Minecraft servers and alike use these to support themselves. Meanwhile we rely on donations and advertisements. Not many people donate these days because of no reward for donation, and most us.. let's be honest use an ad blocker so this isn't a great avenue stream. These allow you to use real money in order to get in-game benefits. Now before we even go any further we wouldn't introduce a pay2win system where you can get exclusive content; just shortcut to different things. For example, paid houses, vehicles, etc.
We want to know the communities input before looking into a platform to support such. The benefit of this to the community would allow us to keep expanding further and further, reach more players with marketing campaigns, and keep the server's running longer and possibly even better (upgrades).
