This might be a little on the side of the main topic but there was always something cool about Crash Bandicoot 100 Apples > 1 Life, and you could grind more to make some levels more forgiving, like semi-adjustable difficulty level based on your previous approach.. And later on — warp zones, you get to choose from a few options so the progression has variation.

Another thing that comes to mind, not sure if a first game to do it, THPS for unlocking movies and later cheat codes, modes and characters for finishing the career. Plus the whole gap marathon for Private Carrera.

Oh, and chanting from Oddword where it had various uses, for saving friends or for changing into enemies, or using special abilities. This definitely was something, because I still remember thinking as a kid, “how cool is that this one ability has so many different uses”.

I wonder what the source of the RTS conventions was. Ctrl num for making groups. Double press to centre on group. X for scattering units. A to stop them. Pretty sure these predate C&C but the only one before that I can think of is dune.

Minecraft singlehandedly created a genre called “Survival”.

I think most of the games around 2005’s Indie Game Boom created lots of brilliant mechanics that’s been copied still.

Dark/Demon Souls. Elden Ring

Rolling to evade incoming enemy attack.

Always thought it being a strange way to do this. Bloodborne and Sekiro dodges seem more realistic.
