I feel like there is a missed opportunity to obtain catsacks by participating in Plaza Minigames or any type of gamemodes, but especially the plaza minigames. Most of the gamemodes don't feel really rewarding, fun and/or are obsolete when it comes to gaining units specificaly.
The way it would work is, you have a >5% chance to get a silver catsack by playing with more than 2 people on an activity. Your chance would increase a little more, if you happen to be 3rd, 2nd or 1st when playing with more than 3 people.
To make plaza gamemodes more attractive, maybe increase the chance of obtaining one a little more.
This might have been already considered on some thread before, but I feel like making a thread like this because I wanna hear what the community would think about the idea.
