By request, I have added two new game modes to the site – Adventure Mode and Hardcore Mode.
In general the Minecraft Adventure mode a player will enter a predefined world where you can challenge yourself to complete an Adventure, setup by the serverowner. Normally you will not be able to destroy blocks or gather blocks as normal, but you can interact with NPC, doors, levers and such.
The Minecraft Hardcore mode is for the people who want a hard survival server – normally in a gamemode like this, you will be banned when you die – for a duration between 1 hour and a few days. You got one chance and it is up to you to make the best of it.
If you have some special categories/gametypes/features that you would love to see on this list, please do make a suggestion. If I get several requests over time for the same thing, there is a very fair chance I will implement it.
