If a videogame tip screen is tolerated it'll become used by everyone including and especially AAA devs though.

Like how ghost kitchens were originally sold to the public as ways for food entrepreneurs with small amounts of capital to start out test their ideas and raise enough for a proper restaurant but very quickly became a way for Denny's to trick drunk people into ordering from them through a delivery app.

For indie devs I feel like some sort of Patreon style membership would be a better idea. Sure the AAAs could and would copy it if it proved profitable enough, but if an offering from a smaller dev blows me away I may spend a buck or three a month and get updates on what the next thing is they're working on if I think it'll help it become a reality. I'd rather see "If you enjoyed this consider following us on Patreon" than a tip screen, at the end.
