Looks like they also had a choice to get the version the rest of the world uses.

Glitchless/no major skips would merely be "hey check it out! I got a sub 2 in RE4 by optimizing my lines and routes with out using ditman or any of the skips that could save a nice chunk of time."
also there are runners who like to run games not utilizing any glitches or skips and just seeing how well they can do with the mechanics the way the developer actually intended.
I'm currently sitting at just above 2 hours for what I call a glitchless/no major skip run so I could potentially get on the board above some runners who have used the skips. I just think a "traditional" or whatever you want to call it category would be neat and I'm not expecting for it to happen nor does it end my love for this game or the game's speed running community.
Also I'm typing this on my phone so.. grammar and stuff .
Edit: Also while we are talking glitches and skips would you guys consider a rocket to the door to activate the light on the other side in the cage a skip?
I personally think that Glitchless/No Major skip should be a category for the RE4 speed running community.
