Over 300 game projects, some made it to a game. I think we need a summary of these games with clear indications on how well they made it as roguelikes. But who wants to do that? It's all mess now, no one knows what happened and what kind of games were made. There were too many of them.
I think 7DRL contest should be a way for developers to get contact in roguelike game development and try out ideas. But it wont make any difference if nothing else happens. If those game projects are left like that, unfinished or too light weight to be anything else than @ moving on screen.
When people talk about how easy it is to create a roguelike, they are talking about 7DRL games. Now try to create a real game with complexity of a major roguelike. Then you can call it easy.
