I think some cool ones would be

-Player kills, ex. 1,000? (Custom named Iron sword?) 5,000 (Custom Named Diamond sword?)

-Time played, 80 days 100 days 150 days? (Custom Name Clock?)

-Fish Caught (No clue, I don’t fish much lol) (Custom Named fish)

-Eggs Thrown, arrows shot, and snowballs thrown.

Those are the ones I think would be pretty good. And getting custom names items for stuff that takes a very long time to get would be a cool bonus for all the hard work.

hmm, ive watched the hermitcraft series and they have the custom achievements as well. they have 2-3 achievements per player on their server. since that would be far too many players for us to do, maybe we could limit it to Staff Member achievements (like how many times you get damaged (Markus on stat tracker, he had like 15k damage done to him or something), or how many melons you crafted (JavaInvader) etc.

if this does not generate enough, we could also make some achievements for legend players (Hardtimez, secon, karim, etc)

Player crafts 600 melon blocks – JavaInvader achievement (“MelonInvader” Custom named melon slice)

Player eats 1,500 cookies – Smokeyriver achievement (“Smokey’s Cookie” Custom named cookie)

Player teleports five hundred times in twelve hours – Heil Hydra achievement (“Hydra’s Mysterious Disguise” Custom named enchanted chainmail armour set)

Player eats 500 pumpkin pies – KetohPie achievement (“Keto Pie” Custom named pumpkin pie)

I notice that one of the options is specific commands entered. With that, perhaps it would be possible to have a command that can not be entered by players unless they get permission to use the command? This way, we could have an achievement system for visiting places ingame. I imagine a button attached to a command block that gives the person pressing it permission to use a certain command so the player has to physically travel to the location of the command block and press the button to get permission to use this command. The command would then trigger an achievement.

This would link to an old post I found whilst exploring the forums.(https://piratemc.com/topic/world-wonders-place-of-interest/) Basically, the post describes a system for establishing ingame world wonders. How about starting this up properly and once the wonders have been decided giving an achievement for visiting all of them? This would encourage players to visit interesting places around the world. So, each world wonder gets a command block and command so that once all of the commands have been unlocked and used by players the achievement activates.

This concept also has potential to be used in other ways. Command blocks could be placed at, for example, all four corners of the map so that an achievement is gained for reaching them. Or every warp could have one so that players are rewarded for visiting them all.

Disclaimer: I’m not familiar with how a server works at all so if this is impossible then at least it was a nice idea

Galaxy said: “-Player kills, ex 1000?”

I think that’s kind of discriminatory against those who don’t pvp much.

Number of warps would be good though, (maybe items bought or sold)

So the most piratey things you can do on this server are:

Sail ships: Achievement for longest distance, if tracked.  If  not: times piloted or times /manoverboard

Fire cannons.

Kill people.

Get pass out drunk.  We could use more drunkards.

Drown.

Walk around with a parrot on your shoulder.

I like Gildor’s idea, but may need to disable tpas within a certain distance or one player will get there and tp the whole crew/server.

Sorry for that, I misinterpreted your bump.

Maybe you could do these achievements like you do the brews, start with a handful and add a new one every other week.  That would allow you to get it launched in a reasonable time frame as you only need a handful to start and let you see how the targets work before adding more.  You would also have more time to customize awesome prizes.
