In Dark Souls 1, you need to get a random drop weapon to start a speedrun. Finding the perfect seed is part of the time investment, you gain a huge advantage in terms of your resources by letting a tool do this, even if the tool had to normally reset Eden by going back to the menu. In Spelunky, an any% run takes 2 minutes, but finding the good shop needed for it takes maybe 2 hours, so during the run, you feel incredibly pressured because the total time investment for this run was 2 hours. Resetting is part of the time investment for a run, whether it counts towards the time or not.The first input of the run, holding R to start it, is done by a tool.
You cannot hold R on Eden, and thereby see like what, 5x as many seeds as anyone playing the vanilla game, drastically reducing your time investment to get a viable seed, creating an unfair advantage.
