I've found a lot of really awesome Forged maps in the Forgotten Treasures thread:

This Turf remake is the best I've seen:

And Construct is pretty cool, too:

Really impressive stuff. Does anyone know how to get that modded gametype with the classic settings? I'd love to try some of these maps with those settings. I do agree that people should be hesitant about Forge maps being in Matchmaking after what happened to Reach. But 3 or 4 wouldn't be too bad. Maybe one exclusive per playlist or something.
