going off your about me ill go over each gamemode
creative - not my expertise but creatives a shadow of what it once was due to lack of updates :/ your plots might still be there tho if its 2018 i forget if the reset was 18 or 19
survival - completely revamped and updated to 1.19 with a bunch of new plugins, tasks, a custom resource pack and just a bunch more custom stuff
parkour - received its first reset since 2017 in may and has completely transformed its style of parkour since 2018, maps are quite uh "creative" now with interesting mechanics and jumps and the number of maps has exploded from what, 400? in 2018 when you stopped to almost 1800
theres a lot to see and do on the other gamemodes as well, new arrivals like prison, the return of factions and most recently towny and even an anarchy server.
