I'd like to do a speedrun of this game but I don't have enough time to do a full game run but I do think I could finish the Abyss Server or at least the first 20 floors relatively fast. I guess it would only be boss fights if you were to use high security so maybe one of the rules could be no high security and no using escapes or maybe 1 escape per floor?

We had a similar discussion recently over in the Cyber Sleuth forum: https://www.speedrun.com/digimon_story_cyber_sleuth/thread/u5rhw

I think the points made there also apply in that case.
