I think that is a great idea. I have received some sounds from a couple of people since joining this forum. 95% of what people have sent me I had already, but it is the 5% that makes it worthwhile.

All my stuff is sorted, or getting very close. I tend to not always keep the video game sounds divided. For instance, if I pull weapons sounds from different sources, they all get subdivided into a weapons folder (blasters, cannons, etc). I don't particularly care which game it comes from. When I'm editing, I'm simply going to look for weapons sounds in the weapons folder. I don't want to have to dig to compare sounds from the Battlefront folder or Jedi Knight folder.

That being said, I'm not even sure which all games I have sounds from, but I have a fairly good idea.
