Which games have speedruns where most of them don't have players talking in the background, be it because of rules, tradition, or something else?

Now that Playground Productions and Mega Cat Studios have released the original Backyard Baseball on Steam, with future plans to release other classic titles of the franchise, shouldn’t there be new rules?

So why were Project64 1.6, Roseline's Mupin GUI, and OpenEmu approved as emulators for speedrunning?

I'm looking for games where speedrunners would rather not do the any% run because the glitches make it way too easy or it gets too technical for people who just want to do some gameplay. Pokemon Gold and Silver comes to mind because the last part of that any% is basically typing names as fast as you can to exploit a glitch, which is why "any% glitchless" is more popular.
