There’d more conflict and the 2015-2024 generation would experience the pain of all their stuff being made obsolete or having to switch.I think if 2024 had been promoted as 6th edition rather than an upgrade to 5th (2014), I doubt it would appear to be less interesting and I figure more people might have picked it up.
Compatibility makes sense to me, especially with WotC wanting to essentially keep the same popular game but ditch “problematic” pre-2024 wording if things. Bit like 2e getting rid of AD&D’s controversial terms.
