For me there are quite a few, the top would be Minecraft and Gran Turismo 2 (on PS1!).
But I recently remembered a small indie game that I a couple of time, called Mario Cars 2 and made by PixelatedCrown.
It’s difficult to find now, but here is a YouTube video to show what it looked like.
Let’s put it this way :
I came for the indie fun
stayed because of the characterization
after finishing it I think the main think that stick with me is the dialogue
I still didn’t figure out how to deal with my death anxiety, but this definitively helped to have some answers (or at least places to look at).
Thanks Chelsea Saunders.
