Hi FedericoGamer15,
I sort of understand what you are getting at with that plugin but I don't see how its any different to the plugin we currently have. With the plugin we have, no one can buy claim blocks with ingame money (donations are another matter to a max of 25,000). Claim blocks are gained at 100 per hour of play as Eli. We feel that this is fair to our players as it means that the longer someone players the larger they build and new players cant 'buy' a ton of claim blocks to then go inactive the next day.
Also if you have a link to the other plugin that would be useful, as otherwise we would have no idea which plugin you would have in mind, I bet there are alot out there!
