Does anyone know about any other self-hosted/open source projects that are like this? As in, “everyone” could find these useful?

Other ones I know about are Mealie (cookbook) and Warracker (Warranty Tracker).

New games just don’t have a ‘punch’ to it anymore. They are not not game breaking anymore.

There is absolutely nothing wrong with old games either. They are the same as they were, which is why reboots and remakes are so popular.

My prediction is that Silksong will be a Nintendo Switch 2 launch title or something similar.
