I have what I think is a good idea. Considering that most or all of the members of this community are aspiring game developers I think it would be a great idea to have a showcase of games made by members of the community. Sure you have the code spotlight and snapshot, but those are weak compared to gamedev.net's game showcase.
I believe that it is imperative to establish a game showcase here at devmaster.net that could possibly increase traffic. You guys are probably not in competition with gamedev.net but I believe that it's about time that another site besides gamedev.net becomes just as large.
Well anyways, not to sway away from the main point. I'd imagine that games created with 3D engines(made by other people/companies) wouldn't get as much praise as games made from ground-up by others. So maybe a set of guidelines should be established.
If this idea gets rejected(for whatever weird reason) then maybe we could hold some contest?
