Thank you for such a detailed response! You asked a couple times if my players were having fun with the game being so easy, and that the answer is "no" is a big part of why I was driven to make this post in the first place. And the way things are going, the players are going to "max out" pretty quick, meaning even just the fun of Number Go Up is gonna fade after just a few sessions, especially with the confirmation that things max out at Tier 3 (which might need a note about what happens if you get a sale on a tier 3 item? A 1/36 chance of a thing happening the game just doesnt know how to happen in a thing being rolled 10 times a session is a lit). An RPG campaign is probably gonna total pretty close to the number of hours in TWEWY, and thats a long time if my players are maxed out so quickly.
Edit: specifically about the set bonuses, that would be fine if all the set bonuses were narrative bonuses, but three of them have mechanical weight and two of them dont. Of the two, I think Favored Primorida is a bit better, in part because its a bit clearer what that actually does and in part because that's probably something you couldnt do without it. But I know my player who ended up with three Metalic Shout saw that and was disappointed compared to the player with three Quickened, who got to generate even more flow.
