Assuming you’re an adult, there are a few Conan Exiles D&D roleplay servers and also some Neverwinter Nights 2 servers if you’re looking to get into D&D but don’t have anyone to play with. It’s also a good place to meet people to play actual D&D on like roll20 or Tabletop Simulator or whatever.

But also, it seems like there are some people here who would probably play a game with you. You might have to run it though. It’s much easier to find players than DMs.

I’m in this meme and I don’t like it

If you’re willing to try pathfinder, you could go with Pathfinder Game Night: Dawn of the Frogs. It’s a 3 session adventure that comes with everything you need to run a game: maps, pregenerated characters, a set of dice, some standees for you and the enemies, and an adventure book explaining the rules and the adventure you’re on.

I haven’t played Pathfinder before (I used to do ADND(2.PF) how expandable is it without official materials? (I guess it doesn’t super matter, none of us have played a ttrpg in years)

All of the rules are actually freely and officially available online here https://2e.aonprd.com/Rules.aspx including every monster officially released, usually with a picture. You’d probably be better off buying at least the core rulebooks to actually read, though.

Also, Dawn of the Frogs only has 4 pregenerated characters, so if you have more friends than that it might get a little complicated.

So to actually answer your question, it depends on how much work you want to do and what your definition of “official materials” is.
