I tried forums (four different ones, including ENWorld), I tried PbP, I tried Roll20 and one of its competitors that I no longer remember the name of (mostly because it was a complete dud), I tried pitching concepts, I tried Reddit, I tried Discord. (Discord produces a lot of games, but not a lot of hits, if you get my meaning.) Started out looking for 4e, loosened that to 4e-adjacent (e.g. 13A), loosened that to other systems I wanted to see (e.g. Shadowrun 5e), loosened it again to "alright anything that isn't D&D 5e that I've actually heard of, and isn't a horror game," then to "alright, fine, I guess I'll look at 5e games and be picky about them," and finally to just looking for any 5e game that might, possibly, maybe play like something I could enjoy.
What, exactly, was I supposed to do better/different? I haven't the money to pay to play, nor would I do so even if I could. I don't have reliable transportation, and even if I did I have terrible social anxiety, so physical in-person games are essentially impossible for me (doubly so once the pandemic hit).
I tried. I got nothing, out of more than a year of searching, regularly, multiple times a week, consistently. Applying to at least one game every week, consistently. The games I got into? They died before they hit six sessions (or the equivalent for PbP.) Often before they even hit four. I put up "looking for DM" pitches. Zero replies. I entered my name in "player looking for group" lists. Zero messages. I even rustled up a group of folks I knew from various forums, but we...didn't gel, shall we say.
And all of this was after I'd already found and lost two actually fun, great groups, the former (4e D&D) to IRL family disaster taking the DM away, the latter (13A) due to the PbP DM ghosting us right as our adventure was about to go somewhere new.
I tried.
Doesn't really work like that. I've gamed with ENworlders.
If you have niche tastes you can't really pitch an idea for what you want to a DM. More likely you're going to put your game out there to attract players.
I found a player I actively wanted to recruit. My game was full and I wasn't the DM.
I asked that potential player what they liked and wanted. They wanted an OSR game so supplied some material for them to look through.
We settled on Castles and Crusades started a 2 player game Greek themed. Word got around and I've got 5 players now.
I live in a small city (130k) in New Zealand. I managed to play in game once with 9 players in a town of 12000.
I would run a 4E game but one would have to supply the materials or be happy with DMG, PHB, MM, pay me and find the players. You get 1 session free as a sample.
From 2019-23 essentially I got my D&D material for free. Store owners gave me store credit via a nominal fee for players. Good night 20+ players 3 games.
I ran the advanced sessions, another DM ran the beginner friendly one she funneled players my way and the other DM she had the largest group with 8 or 9 players depending on the night.
I used to help with MtG organization. One year we sent the second largest contingent to nationals from out smallest city. One of the lads won and went to the USA.
Some of those kids at the time are now mid 30s. One of them are in my game. 20th anniversary this year

.
If I get to play odds are I've trained that DM.
Another games store is trying to get games organized. As I understand it they can't get them up and running.
I don't play or run online it's not worth the hassle for me. NZs nicer than rando's online.
When I was involved in Magic it was another prime player recruitment place. Talk to people about 1 in 10 were interested in D&D but our pool was 20-40 people depending on the day so 2-4 players right there.
I've basically described myself as LN DM. There's a reason for that LG games tend to be try and keep everyone happy but often devolve into CG games and fall apart.
Back in 2008 or so our MtG group chipped in and bought gaming tables. They've bounced around the city since then but turned up at a store and I was using them into 2023.
MtG and D&D players are often similar. Not very organized, turn up when they want (fine for mtg, D&D not so much), and most don't want to do much themselves.
Both of my games are 3pp material because that's what the players chose this time around. Both are curated in what you can play and content allowed.
