I dunno, I defer to someone far more experienced to me as to whether they would like to revisit their first map. It seems to me like something some people would love and others detest.
There's no way I could make it balanced: http://forums.tf2maps.net/showthread.php?t=21943
I actually don't like that thread because it's easy for something to get brought up once and immediately forgotten.
Who says?
That looks like it has potential!
there could be rules around how similar/different it can look
You can't make a crap map into a mann map while restricting differences.
Haha, I pretty much did exactly this with koth_rocktop. Not my first map ever since I mapped for other games before TF2 but it was my first honest attempt at a TF2 map.
The idea isn't bad, maybe it could even be expanded to unfinished projects in general? Or maybe collect a couple of donated unfinished/abandoned maps, and people draw numbers to select which ones they want to complete.
