I think a lot of it is wasted effort. I doubt many people read all the intricacies of these highly detailed OPs. I sure don't, even on games I'm interested in. Who has the time to read all that? You get a bunch of people saying "great job on the OT," but I doubt more than a small fraction actually read it all.
I really think the solution is to actively discourage that kind of perfectionism and lower the bar. Stop trying to impress other people by loading the OP with everything you can think of -- breakdowns of every character, all the weapons, tons of images, etc. That's what the thread is for. If people want to research and post stuff, you're killing the incentive by putting everything in the OP. Besides, it's just TMI.
Here's what an OP should have, imo:
1. A simple, straightforward title. Include release date/window and platforms if possible. Ex: "Ghost of Tsushima (PS4, July 2020)." That's it. Don't worry about a funny subtitle. Be funny if you're funny, but a simple title is better than an obligatory "funny" one. Also, a funny subtitle sometimes focuses people's attention on one aspect of the game (imagine the TLoU 2 subtitles, for instance) and so pre-shapes the discussion. Better to start neutral and open-ended, give the conversation a chance to evolve naturally.
2. Include a basic description of the game. This doesn't have to be elaborate. It can be a few sentences. What kind of game is it? Who's the developer? Anything significant to say about graphics, release date, that sort of thing? Maybe include a few bullet points from your reading. No big deal. People do NOT need all the details.
3. An image or two from the game. You don't need any skills for this, just an ability to use the "insert image" function on the menu.
4. A video or two, a trailer and gameplay if possible. Again, you don't need skills for this, beyond cutting and pasting Youtube links.
That's it! The end.
Remember that the purpose of an OT is just to open the discussion. The purpose is not to thoroughly document every aspect of the game and flood the reader with imagery, so that people will be impressed by what a great job you did on the OT. That is complete and utter overkill.
