While I would love this, I dont agree, as it wouldn't be fair to whoever payed money for it. If we go and get it for playing a game, and they payed real money, I judt dont think that's fair.
What the current noobstown vip+ is, is against the EULA to be sold, so it would either be given for free in-game, or revamped into a basically simplified cosmetics perks only (and then the ones who have vip will go: but i want cosmetics too, why would i pay twice for vip)..
I think there's nothing against giving it away to those who worked hard for it. if you get into the top10 for 12 months, you have the 12 items needed to exchange against a voucher that lets you execute a rankup command once. If you got only 11/12, tough luck.. it shouldn't be easy. i agree.
any future ranks should just be invisible, but stacked up on top of what players already have. Visually nothing changes, but /player username, could display: ranks: a,b,c,..vip,content.,staff..
and a /ranks GUI could display the eula-friendly things you can buy through shop.noobs.town (which doesn't exist now)
