I want to add a 5th to thisVoted Other, because 5e is Starbucks.
1) Ubiqiutous within its niche. There are other coffee places, even popular coffee chains, but Starbucks is everywhere. Just like 5e within the TTRPG space.
2) Mainly offers one thing, but a ton of modularity within the space that it offers. 5e mainly supports one particular play style (DM focused story play), but gives you a ton of options within that space.
3) You can go to Starbucks for 2 min, or you can go for 5 hours (pre-COVID, anyway). Likewise, 5e works well for both extreme casuals and for dedicated TTRPGers.
4) Starbucks both helped originate its niche (upscale coffee place) and remains the leader within its space, again much like D&D as a whole.
5) Within the craft coffee business Starbucks completely and utterly dominates, but within the coffee business they are a very distant 3rd (IIRC).
