for me i like:
-non-pvp
-no griefing
-survival (non-pvp, no griefing)
-creative
-(must) parkour
-(optional) maze
-also pvp arenas are good cause then pvp ppl will like that :p also a portal to a survival where griefing is aloud
-minigames/adventure maps
ppl like to make towns, but when its a big town its kind of annoying because itll take forever to get out. sure its nice to explore but....eh idk your choice
-commands: /tpa /kit /back /sethome /home /spawn ...etc.
-and the plugin so you can lock chest with signs and for griefing your choice what plugin u chose for that
....yeaaaa...so those are the things i like in the server xD
