Generally maps from other games (minus TFC of course) don't work very well in TF2 due to the very specific design required.
Actually, and speaking from experience, i find even TFC maps convert terribly to TF2.
The scale is different, the speed and general mechanics are different. Not to mention the lack of ladders. Sentries have reduced site ranges so previous sentry locations are made redundant.
I would recommend people never port a map for these very game breaking reasons. Trying to convert from TFC to TF2 was
perhaps fun if not at times frustrating, trying to deal with the same issues Valve experienced in replicating A/D CTF mode; and ultimately dropping the mode altogether for CP (i speak of course of Avanti).
Trying to replicate this classic was probably a mistake, if not an experience to learn from. I could have produced a working map like Youme had in the same space of time, as he produced pl_hoodoo.
So i'm currently an individual with a broken port to my name and and two alpha's, whilst i would like to have submitted a working map to the public when it counted most.
