Why isn't the game B for speedrunning?

BTW I did some research and found out that donkey kong was released in July 9th so please add that.

That's the arcade release date..
Famicom/NES
JP: July 15, 1983
NA: June 1, 1986
EU: October 15, 1986

Ok.

yeah add game b please

normally, i wouldn't be against it, but...

i once asked the SMB community to add 2nd quest/loop as a category, and their answer was: its too similar to be interesting... and even tho i strongly disagree, in a sense, they were right, it IS very similar and in term of routing and execution, there IS very little differences, even tho there are some...

point being, it eventually became a meme category (now called categories extensions) and there's barely any interest for it for the very reason that they were right in the 1st place...

now, i've personnaly did some runs of Game B and my PB is almost the exact same, and i can tell you from experience, Game B is the EXACT same as Game A, the only difference is it takes longer, meaning it takes more attempts, to get a good run going, since the RNG is a bit worst, hence why its called Game B aka hard mode, but other than that, its the same experience in terms of routing and execution... there's no noticeable increases in speed, number of barrels nor enemies, nothing...

so unless i can be proven wrong and that there's is some differences, there's no reason to consider a board for this atm...

PS: keep running Game B for yourself if you're enjoying it, put your archived runs on youtube like i do, and who knows, maybe one day... maybe someone will make a good argument in favor of Game B, but i wouldn't hold my breath!! ;D
