There are a lot of neat areas on a game's page... but what about an area where users can contribute information such as controls, how-to-plays, and perhaps other advice like a walk-through? You can even reward Viz for the contributions similar to what's done for reviews. The more info, the more Viz. If people rate it well, that would give the contributor Viz as well. I think this would really come in handy on those really old, obscure games in the RGR. Some of them are very confusing and have no real documentation if you're not fortunate to have an instruction manual (and in the case of Japanese games, for example, even if you had the manual, you might not be able to READ it). Buying most of my games used for most of my life, I know very well what it's like to play a game and have utterly no clue what I'm supposed to do and have no help offered anywhere.

Crazy Li : There is a walkthrough area. It is located here:
https://www.vizzed.com/boards/forum.php?id=103&sub=Walkthroughs

I do believe it is linked on the game pages too.

I didn't notice any such link from the game pages I visited thus far. If it's on any, maybe it's just on ones that have actual Walkthroughs posted? It also did not appear as though you could directly submit any sort of game help from a game's page. Though thinking more about it, I guess you would use the game's forum to do that?

Yeah, there is the option to create a walkthrough thread from the game page via the link to make a thread on the game page and selecting the bullet Walkthroughs for that sub-forum. That will automate the thread to the Walkthroughs sub-forum in Game Discussion.

Non-staff won't be able to directly add stuff to game pages.
