If someone wanted not to play your game, they just wouldn't. The whole point of a speedrun is to engage with what's there.
The result of this was that runs were 46 seconds and people quickly stopped caring.
But the reality is that _EVERY_ game has mechanics with unpredictable consequence and emergent behavior.
Different games take to being speedrun differently, and every game CAN support runners!
What if you could see your timer live and manually program in split points? Compare to historical times on the same cart?
