I only really have a single gripe with #dnd #5e. Sure, it's not perfect, but basically all #ttrpgs have their issues.
My problem is simple: #dnd is the most famous #ttrpg out there... and it's terrible for new players. You literally need an existing expert to teach you the ropes.
There are way too many mistakes you can make as a player, and basically no guidance for the DM. We all know that the encounter balance is terrible, but new DMs don't.
A bunch of friends all deciding they want to try #roleplaying for the first time and picking up D&D is the easiest way to have them quickly burn out and decide "it's not for us".
So when I find people that are interested in #ttrpgs, and I can't personally GM for them, I recommend the following games:
1. Edge's #StarWars rpg game (used to be Fantasy Flight's). The Beginner Boxes are absolutely insane, it's a very popular IP and since it's not DnD it doesnt get as polluted by any preconceived notions they might have about what #ttrpgs are supposed to be about (I've legit had people said they didn't want to play DnD cause they didn't know much medieval history...)
2. #Fate Accelerated: super tiny booklet that the GM can understand in a single afternoon. Simple mechanics. The good thing about this option is they are immediately playing a "full" game. Still wish there was a beginner box or beginnner game sort of thing. If you know of one, let me know!
3. #Pathfinder2e, which usually just happens when they really really want something like D&D... and #pf2e has an amazing Beginner Box! I also find the 3-action system very intuitive for players that have like played a videogame. Once. Ever. And encounters being balanced makes it less likely the #GM has an aneurysm.
So when I get asked what I want from #onednd... I just want a good Beginner Box! And tools so that DMs don't end up crying after their epic boss falls in a single round...
I just want people that come to the hobby saying "I've heard of D&D!" to be able to play...
