>A game can take a very very long time. Turns might even take days or weeks on particularly elaborate ones. Thus there is a major time commitment during which you must leave the game out and setup for an extended period of time. The Campaign for North Africa is probably the most extreme example of this. https://en.m.wikipedia.org/wiki/The_Campaign_for_North_Afric... A "proper" game requires 10 players and an estimate…
I don't think anyone is on record as having completed a single game of Campaign for North Africa. Likely not even the author. Which I guess makes it a game only in the theoretical sense.
Today any group playing it is more likely to play it using (the open source tool) VASSAL (here is the free module to download to play CNA: https://vassalengine.org/wiki/Module:The_Campaign_for_North_...). I saw a thread on a wargame forum just a few weeks ago looking for players to start up a new game. Playing online probably makes it a bit more likely to be played (but also less fun than to gather around a huge table IRL?).
(Aside: By tradition, an old "gentlemens agreement", between the wargaming community and wargame publishers, when playing a game online with VASSAL every player is expected to own a physical copy of the game. You are not supposed to download the CNA module to play it for free without owning the game. There is no DRM or other attempts to police who plays what, but as long as the system is not abused too much the publishers are happy and most keep allowing those tools to exist. It is a nice contrast to how copyright is handled elsewhere, including in more mainstream tools for playing online boardgames. I guess it is only possible in a small niche hobby like that, and possibly only because the tradition started last century before there was big money in selling digital versions of boardgames.)
