Yeah, we don't have a category on that at the moment.
My opinion is that there should be a category of it's own, like HD+, No HD+.
Because HD Edition is Restoration of Erathia, it stands out.
I bought my copy of the game on Good Old Games.com, there you get all 3 expansions. While I have the choice between all RoE, AB and SoD campaigns, the Shadow of Death is overruling the previous ones. It means that the maps we play online and in Single Scenario have the later changes that HD Edition 2015 on Steam doesn't have.
It would be cool to see what sort of runs you can get on the HD Edition 2015.
Do we really need 2015 Steam edition as an option?
Does this edition has any differences with Complete or ROE/AB/SOD?
I see that there are only two runs (one without video) in Steam category, and both are in Tutorial, but this option is visible everywhere. So I vote for removing this option and move runs to "No HD-mod".
And rename "HD" / "No HD" to "HD-mod" / "No HD-mod".
It's an option because it's a version of the game that's available if someone chooses to speedrun it, same as any game with a port or remake.
