That’s a big undertaking, good luck! I’ll definitely be trying it out once it’s playable.
Having a nice list of characters you want is cool, but for now I’d say really pick two (or even 1) and try to get them prototyped and make them feel good to play.
I get this. Loved Tri and Freedom Unite, played a decent amount of 4, some of World, and barely started Rise.
They’re always exciting, and I don’t dislike any of the games, but it’s just a lot to get going, really invest the time, and get the value out of these.
