not sure what kind of internet you have but it took me around 20 minutes and I've got some of the fastest you can buy. It is a quarter of a gig after all and I don't imagine Pragma has a super-server, so just give it some time, it'll be worth it.
Also, I was thinking after looking at a very early post where people were talking about selecting a character like one would do In the actual MarioParty series. Because of some things in the game, I don't think that would work. But how about this, which I was inspired by that idea. You could sort of get it but also give Pragma more cool unlocks to tease us with.
There are some sounds that are used in many games, such as jumping, walking over various kinds of terrain, swimming, climbing, and stuff like that. We could get soundpacks in the rewards room that would swap out those common sounds for others. These would be thematic and would sort of allow you to turn your random adventure player into something else. For example, there could be a knight set of sounds where the weapon would be definitely a really dramatic sword noise, moving would have some clanking armor, and there would be some underwater clunking sounds while swimming and so forth. There could be a clown that would have wacky cartoon sounds, a fairy with cute magic sounds. A princess/lady with dress-swishing sounds when she walks instead. creepy sounds for some Halloween/vampire/ghost/zombie. Anime sound effects for a samurai/ninja/mecha character, animal sounds for a bestial character and so on. The sounds couldn't be overdone as they might interfere with games but it would be a nice bit of flavor.
