I used to hang around a few years ago in a RPG Maker forum, it was fun. The forum was actually centered on a piece of software that was very flexible which allowed to make any combination of character. You see, the major problem with making an RPG on RPG Maker was the lack of sprites, so this amazing piece of software that could arrange a wide variety of original characters was great.
Around the forum grew whole collections of sprites. Most of them were ripped from every conceivable SNES or GBA game, and they were available for your use. Sometimes, a talented artist would show how in photoshop you could make your own character since the spirtes were only 8x8 or 16x16 or something. I believe what you downloaded was called "palletes". Each "map" had to have a unique pallete that contained about 30-50 textures.
It was actually quite hard to make a game, because of the way RPG Maker worked you had to choose only 1 pallete per map. So you would go for months downloading all the software(translated to english btw), palletes, cataloging everything, and you'd end up with thousands of textures, all 16x16. A door for example took 4 textures, which to the naked eye were just scrambled pieces of pixels. If you wanted to create a V-shaped roof for your house, you'd use the same textures but reverse them. It was all very confusing. And of course you had thousands of them that you needed to whittle down to 30 or so to build your first town.
Something that was very appreciated were people who released demos for their games and provided their game "open-source", everything was available for you to poke around, and most importantly the palletes were there to be "re-used".
And of course since most things were just ripped from other games, good luck having it all match together. For example, the FF6 palletes were completely unique and horribly complex. I developed a deep respect for the makers of that game, as most RPGs. The other problem once you put it all together was that it looked like shit. Basically Avernum-like towns. If you ever walk around FF6, you will be amazed how nothing is symetric and how everything melds into each other so perfectly, all while having secret passages and more. It's nothing short of genius.
This was also another common problem to the community, so common that some people released some amazing tutorials for making interesting locations. They'd show how you'd start up with a very single map design, then distort it a bit to make it look natural, that add some objects, then add some people, then add some new designs etc. Basically it takes talent and time.
Some people were experimenting with the scripting and coding available to RPG Maker. They were able to make real-time action-RPG combat for example, which RPG Maker never had. There was a lot of buzz in the community, yet you sort of realized that making a game wasn't what you believed. The most popular sub-forum was probably the RPG-Preview sub-forum, where even yours truly posted a topic. And even with all the help and all the resources, I'd say that 95% of things posted there didn't make it to the demo stage, while 99% of them didn't make it to a full game, that's the reality of it all.
And I didn't even mention anything yet when it comes to sound, music and graphic effects. What I learned the most about that place was how important a community is. You had selfless people releasing their demos open-source, ripping palletes from every game imaginable, famous "original graphics artists" that worked for the most promissing projects, people posting tutorials, hell the forum itself was spawned from a great free program. I was even thinking of being an original texture designer, even though I knew nothing about it. After all, how hard was it to make 16x16 textures in Photoshop? In a year or two I'd probably be good at it.
But because of the extremely high failure rate, it all sort of felt pointless. Making games when you even have such a strong platform as RPG Maker, its resources and the community around it is still very difficult. Yet at the same time, a group of 5-10 dedicated people could probably create something special. I just think that before they start, there should be a blood-bond ritual between them.
