I’m a big fan of Endless Ocean 2 which came out in 2009 but you need to use Dolphin to run it on PC (also torrent the disc files unless you can find a disc copy). Also it’s still the best diving game out there which is kind of crazy considering how old it is

Boost has always had ads, it’s one time purchase removal

This is unrelated and we are going to face a similar decision to beehaw’s soon as well (or we already are, considering I saw at least one post about it)
