My preference is there is not a glitched leaderboard split for DOS. Especially with no active runners and its already a small leaderboard.
In the finer detail, it is nearly impossible to police glitchless in a meaningful way for Atreides, as it would mean outright banning carryall repairs to avoid any accusation of ghosting, which is a pretty arbitrary restriction on your gameplay. Your run can get invalidated by bad luck.
Its slightly better for Harkonnen/Ordos but you can still easily accidentally ghost with a starport for some period of time.
Darksniping is easier to define but you are also likely to do it by accident and you need to define a complex rule like "For each enemy faction, you must be aggrod by an enemy unit before attacking any enemy structures".
The game is just a bit too glitchy and the glitches aren't easily avoided.
Nice. Curious, is there AI manip on the deep point placement, or can you just go 3 fielder strat?
The default category is MS-DOS which has no overtly obvious specific DOS rules, so its quite easy to make the mistake just pressing "show rules" and seeing the short common rules and thinking thats all there is.
I suggest adding "runs must be run on MS-DOS or official Dosbox" to the DOS ruleset, so new genesis runners get the hint to go looking for the genesis rules instead.
The closest thing is spam tabbing between units with the tab key. Using this with the keyboard hotkey to select orders, you can at least bulk move armies quickly. Its not great for battlefields because tabbing tabs through enemy units and structures as well.
