Currently ZDoom.org hosts the Spotlight and the About pages for all things about ZDoom. But, especially in recent years, GZDoom has become a platform for new, independent games. We know Harmony, but there is so, so much more. Many of these games go to Steam, but as the hub for all things GZDoom, the only way to know this is through people making lists. Gez and I both have a very extensive list of these at hand. What is missing, is a central hub that showcases GZDoom the best.
Because GZDoom has evolved beyond just a engine for Doom games and even beyond a framework for mods into a fully featured platform for independent games, i suggest a Powered by GZDoom page, listing all those mighty fine examples that are now achieved through GZDoom.
I realize crafting such a page takes a block of time that most likely is now used for other, more important matters (Such as Raze).
