Unfortunately, it's always the way with games/mods. It's always the lead who gets the most credit. Whether they be the person who's name is on the box, or the lead designer, or producer. What of Oggie who created so many of the wonderful graphics in Civ4?
It's these people who also deserve the praise. The people who contribute to components of the mods. People like the Lopez. As a lead myself on some projects in the past, I ALWAYS ensure that anyone who contributed to the project gets their wrap, either in-game on a credits screen I made or in the main documentation. Aside from that, I can't think of any other way to highlight that the project was a combined effort. Take my combat mod as an example. In the main documentation I list every person who contributed to the mod, even to the testers and original discussion.
On the other side of the coin, if someone then uses any component I've written, and it produces a great project, then I am happy that my work has contributed to a great product. So I feel if as long as the project leads do everything they can to highlight the fact it was a team effort, there really isn't too much else we can ask for as contributors.
At the least, we at CivFanatics know who they are and appreciate their work.
