More Event Ideas (Robux, free rotation, and by purchasing tickets)
So basically, more events that can spawn. In the free rotation but also make them Robux so players can choose to spawn them more often.
Editing to add, end-game users have a lot of Blue and Gold tickets they cannot use. Please make some events purchasable for tickets to help eat those up. (Idea for ticket purchase credit to Indigold)

Some ideas could include, maybe:
1) Alien Invasion that spawns more alien packages for a time.
2) Truck Delivery! A delivery truck pulls through and parks for a short time and players will be able to grab some random packages off the truck, that have a higher chance of being something rarer.
3) Package Rain! Spawn a short rain of random packages that fall all over the warehouse.

Editing to add ideas from comments or just my brain:
4) Star Blast! Falling stars bring shooting star packages!
5) Ticket Rain! Choose blue or golden tickets to rain across the server, blessing all players with a portion of it, OR drop them on the ground and players must run to pick them up. Not sure which version I prefer.
6) Gold Ticket event https://discord.com/channels/1405324888033464380/1501257528099475506/1504497989320704131

Leave more ideas if you have them!
Star Blast! Falling stars bring shooting star packages!
I LOVE THIS
added that to the main suggestion
yeah, i can see the end game getting a little... hoarding of the tickets with nothing left to use them on
More Event Ideas (Robux, free rotation, and by purchasing tickets)
I love being "rich" in games and joining and spawning things for other players. Brings me joy
Just like gamepasses, I would LOVE the ability to gift gold tickets to either a specific user in the server OR make it rain golden tickets that are distributed over all the players there (like, everyone gets 100, 300, 500, etc). This would be a Robux option. When I have the Robux, I LOVE to make others happy in games that have this ability. Doodle World, for example, lets users purchase a Gem Rain (their special currency like the gold tickets). It makes users very happy, and it can be a fun giveaway option for content creators.
Second, third, and fourth images are from Doodle World to help show what I mean as an example.
Idea for gold tickets as a chance to spawn with the packages, or the event for a Gold Ticket to be purchased for Robux. It would put up a notification that it has spawned and would spawn somewhere on one of the conveyors. First to get it gets 10 golden tickets.
Idea credit to how Laundry Sim has gems spawn randomly or purchase the event for Robux.
