I love this idea, it feels very nostalgic and makes me want to dig up some of my old games too, haha! These were fun to play to see your game dev origins. The Memedom one was my favorite; the shark fight was really challenging but I had fun and did manage to beat it on my last life!
That's cool that you were able to launch them all from Godot (I really like the PS1 themed cases too)! The one issue I did have though is that because there's music playing on the hub screen in the Godot game, it did clash with the Unity games once they were launched so I ended up having to close the Godot launcher between each. So if it's possible to make the music turn off once a Unity project is launched that might help!
These early games really do show how much your game dev skills have grown too, so like you said, remembering your roots is important, I agree!
