I Personally joined MV for skyblock and skygrid and when skygrid got removed at the revamp I became a little bit disappointed so I would like for y'all to look into adding skygrid back. I would like to see possibly a money or resource reward for finishing parkours in all the game lobbys, and to make sure the people do the parkour legit we would have to make them step on a pressure plate to deactivate /fly and other commands to help them win but also make it to where the reward sign or button or whatever it is to only be able to be activated once and only if the pressure plate was pressed.
People did play skygrid back in the day (from what I know), and quite a few would like it back. It died because it was never updated or anything. Support for skygrid, neutral for parkour (I don't feel it's needed and could be abused)
As @i_am_youtuber stated, It was good back in the day and if there were added features to it such as silkable spawners and shops where people could generate money to build and buy new things I think it would go very well.
