Hi Jason, nice to get a reply straight from the top. Those rules seem like they would be very effective, but like you said would require a good group of mods to maintain. I do want to elaborate on what I was talking about regarding submission guidelines though, because I think they could be just as important as having a good mod team. In my opinion, there were quite a few issues with the consistency of the content submitted to thegamesdb, such as:
1. Lots of duplicate or hacked titles cluttering up the database.
2. A very broad range of quality for the box art. I realize that it's not always possible to get a totally clean scan, but the quality of some of the images was just terrible.
3. No set resolutions for box art. Having consistently sized images is the first step towards having a decent set of box art. The size could be chosen based on the physical dimensions of the systems original box and some PPI value.
4. This is probably my biggest issue with the other databases. The game descriptions need to come directly from the maker of the game, and in the case of boxed titles, it should be the text directly from the back of the box. There are so many games listed in other databases that have descriptions that sound like someone casually talking about it to a friend, instead of the colorful, entertaining language that's usually on the back of a box.
That's most of what I can think of off the top of my head, I'm sure you've already thought about some of these problems. At the end of the day, I'd really just like to see a database that had a higher focus on quality.
PS. LaunchBox on Linux would sure be nice!
