Perhaps part of the elitism and silly questions problems is that the newbies don't think it'll be hard. With a name like "ROM Hacking", if you know what that even means then you'll know there's work involved. However, "Game Development" sounds like something anyone with an "I wanna play all five regions!" attitude could do. After all,
obviously the hard part in making a game is knowing what you want to make, and I wanna make all five regions!
I'm not suggesting a rename of the section. I am suggesting, however, that some guides on how to go about game-making be put somewhere in a place people will see them. You know, "get an idea, get software, learn software, plan out game, learn software, make maps, learn software, event maps, learn software, blah blah blah". Give them a way to get going, and it will not only show them how much there would actually be to do, but also tell them what they should be expecting at any given stage (i.e. they won't have demo within a week). With more realistic expectations, they may become "cooled down" and develop a more appropriate attitude towards their game, resulting in fewer daft questions (which are only asked because they're jumping ahead of themselves).
I mentioned elitism, and I think this would also be reduced by the guides. People who stick around after reading them and finding out how much there is to do will (should) gain some respect from everyone else, thus weakening the expert-peon gap (how can you deride someone if you respect them for their commitment?).
What GD really needs is a place to start from. Being a Pokémon site, we're bound to get all sorts of complete newbies coming in, and they've got nothing to look at to help them get started. It's fine even if this starting point is a collection of links to other places with better tutorials/software/ideas, but without a starting point people are just going to dive in at the deep end and get lost really quickly.
I should point out that the wiki only lists games that were made with Essentials. SPEE isn't in there, for example. The wiki itself is also out of the way, and people wouldn't expect to be going there to find out what GD has to offer. We would still want a stickied thread here listing the games with demos.
