One of the difficulties we had back in 2017 was with ping, since doom was designed for lan play, not internet play.
Clients would wait between for player data to come in before advancing to the next frame. So if you weren’t within a few 100 km of your playmates, the game would both became a slideshow, and unstable.
With friends all in western europe, it was tolerable. When outsiders were added (brazil, australia?) it was a completely different experience.
If you want to try playing online again, I’d recommend a source port that is built for internet play.
If you want a more authentic experience (original builds + dosbox + an ipx tunnel) then be prepared for the above!
I also said that this was “one of the difficulties” – there were others, such as compatible engine versions, and having people available to play at the right time.
That said, I would enjoy playing this again online with the club, as it was fun and memorable.
I also fondly remember twice doing a full coop playthrough with club member bitrot/byterot. We were both skilled at the game, so it was breeze, but it still meant a 4 hour marathon and a late night to get through the 30+ levels. Good times. :o)
