Well, time for a view.
It feels like the intentions of the map has been put incorrectly. For example, Jake and Dairyking can't be blamed for not using textureblending back in those days (as there wasn't yet), but there definitely could be some right now.
The lighting seems broken. The original had a lot of ambient lights which gave it a cold and mysterious atmosphere. This version seems to lack that.
I also noticed certain lightmap errors which appear from skylight, like in the next screenshot. This can be fixed by the command
skytexturelight 0.
Also; what about noclipping those dark grey stone platforms? They seem to be purely decorative yet you bump against them when trying to get on top of it.
About the clipping any further; the trimming around the doorway in the centre of the map isn't noclipped (while it is in the original). Players get stuck in it when trying to take the corner (forwards or backwards).
The ceiling of clip on top of the map is pretty broken; Players are able get on top of the ceiling of clip by using the Quad, a YA and 2 rockets and a teammate. However; they could also stick to just the centre of each base and stay on top of the roof.
In either case, just fill the ceiling of clip so no one can actually get on top or within it. This also increases the PVS culling of the map.
The new style of geometry feels like being copied from curvy_castle (that diagonal windows towards each other), while the rest of the map isn't having such shape at all.
The map contains 2 quaddamages which feels way too much for any map. Perhaps a HB for each team would be reasonable, but not this.
The original had 8 playerstarts (which is relatively low), this one has 26. That's quite a good job, although that's about only 6 playerstarts each team, as that could be more.
It's a very nice attempt and the original map surely could be a ctf map or capture map; but not like this. Old deathmatch maps shouldn't be hijacked and turned into a ctf maps as they have a different gameplay and purpose. Adding even some bases for capture or hold feels wrong also.
P.S.
I'm sure there once was another map in the very same style (not nmp10). Can't remember how it was called though.
