@kdrnic I totally agree with you, the first and last maps should be a team effort, that sounds like fun!
You didn’t mention E1M9, the secret level. Perhaps that can be on reserve for anyone else wanting to join the fray? Otherwise it can either be skipped or become a team level.
We can also use the number of weapons, items & monsters of the original levels as a *guideline* when placing them in our levels. This ensures play at a similar difficulty than the original game, and saves time fussing with balancing. Totally optional.
(List of Things for each level is at https://doomwiki.org/wiki/Knee-Deep_in_the_Dead – click through to the level, then scroll to the “Statistics” section)
