California Fire Relief Bundle - Cook, Serve, Delicious!, Hidden Folks, Octodad, Tangle Tower, TUNIC, and 417 other items ($10+ USD)

All proceeds, minus processing fees, go to CORE (Community Organized Relief Effort), a Los Angeles-based organization which offers direct monetary support to survivors of the fires, and supports projects for fire resilience in affected areas (and potential disaster zones).

According to a SteamGifts comment, 187 of the 422 items are video games.

I assume the online Bundle Browser will probably add this in soon, and there's always Playnite to help with library management if Itch's own app isn't cutting it for you.
