Thanks for your reply, and I completely understand what you mean by the huge amount of Factions servers, and how they're all the same, and I have already taken that into account.
With my factions server, I will have a large number of custom enchantments that players can apply to their items.
The prison server will also have some of these custom enchantments, which will mainly be for the pickaxes and weapons, and there will be mcmmo which I do not see on a lot of servers.
The skyblock server won't have any custom enchantments because I would like it to be kept mainly "vanilla". There will however be a shop that contains items such as iron or gold, which are not easily accessible or are impossible to get in plain vanilla. These items will be quite expensive and for the players to purchase these items, they will need to create farms to earn/sell items and purchase items from the shop.
Finally there is the Arcade server. This server will be connected together with roughly 5 other server, completely custom coded. Some of the minigames include tntrun, sword switch, CTF and more
Hope you like my plan for this network
