Gameboy color dinosaur JRPG / metroidvania that seemingly no one else has ever played. Called Dinosaur’us. I had to google the name there and it turns out there is a wikipedia page so it’s not totally obscure - https://en.m.wikipedia.org/wiki/Dinosaur’us
I loved this game as a kid! There are surprisingly few good dinosaur games (although admittedly a lot of good dragon ones).
Edit: only ever released in the UK - that explains a lot of why it was so obscure. The ROM is on emulator sites though if you are curious.
Envious of Argentina. We were 5th in the world once but have never been able to take the next step in terms of collecting the big scalps.
