Infinite really ought to have a catalogue in the store for purchasing items. Many games combine a catalogue with a smaller rotating selection of highlighted items- that would be a massive improvement albeit still a dubious method of sales.
The only reason to have a rotating selection without a catalogue is to exploit fomo from people who struggle with it most.
It seems clear that the game’s current storefront is not designed for gamers who think critically about purchases, but is designed for maximizing profits made by whales with poor impulse control; vulnerable people, kids, etc.
Please make Infinite have a fun and inclusive customization element for all. I’m certain 343 can still make profit from that- it’s a tried and true method and they have access to people who know how and want to make it happen.
