>>23800052/gif/: Lets you recreate a single action over and over again, typically only a few seconds long. This allows you to both work faster and with greater efficiency (you move almost exactly the same each time) or you can just repeat the action another person takes if they do something hilarious.
/v/: VIDEO GAYME- Once per month you may erase the memory of any video game you wish, allowing you to play it for the first time again. You can't do this for the same game every month; but you can erase the memory of a game you already erased every year.
/vr/: Allows you to summon forth a game, once per 4 months, to any console (or primitive computer) ever. It comes in the original format the game came in though, so you need the original console to play it, or whatever.
/vg/: You may create a community of active, not obnoxious posters on /vg/ about any game you wish. There will be discussions, arguments about the game's lore and mechanics, and even some new le funny may mays will come from this thread. It is guaranteed to last a year, after that it may start to fade depending on activity of the community and actual quality of the game.
Once one of these general threads dies, you may create another one, but you may only have one active at a time.
/fa/: You gain a colorless, odorless jelly substance that you may spread on your skin to create any clothing you want. When you are finished, just peel it off and put it back in the container. This allows you to keep up with fashion trends without spending a cent. You don't get any more jelly, but you start with a decent amount and it should last you a good 10-15 years depending on how you store and use it. It may even last a lifetime.
/sci/: You may gain one doctorate degree, of your choosing, and the skills and credentials to match. You acquire this instantly, no money or time spent.
Some more. I'm having a hard time thinking of the boards I never go to, or who are smaller in scope. Hope somebody is saving these.
