The screenshot and description are looking interesting.
Content
The content isn't correctly packaged. Don't put a folder called "Rivals" in it, as it isn't existing for other people.
Also, don't use the png-format for the loading-screenshot of the map, as it can't be found by Sauerbraten. Just use the regular jpg-format.
This map is definitely not designed for a mode like deathmatch, even being played with more than 100 players. It also isn't designed for Red Eclipse, as I can load it in justice-edition.
Theme
The map has a very interesting theme, as you've used 2 themes separately from each other. This is a though challenge for some mappers.
Texturing
The texturing seems to be fine, but could be better on some places. Also, I'm missing texture blending on the landscape.
Geometry
The geometry can still be improved greatly. As you stated "you might need a good to play it" I have a video card which handles Cube Engine 2's maps pretty good, but I was getting only 26 fps at some places. So better said:
"This map is just against the idea of Cube Engine 2's octree system." This could be improved with the next things:
Those windows (for both bases) aren't bad looking, but are having way too much triangles to be used that often. Same counts for those "crossed bar-floors". They could also exist out of 1 line of diagonal bars, instead of 2. That would half it's triangle count.
Those pillars look good, but are also having way too much triangles to be repeated that much, on a map which seems to meant for playing. Try to make it less detailed and I'm sure that would pay off.
Also, removing the glass from platforms which contain diagonal bars already would raise people's framerate incredibly. This also counts for all windows.
Lighting
The lighting is also, pretty good compared to your previous work, but still could use some tweaks, as torches in the castle are emitting some greenish light, while a red light-source is emitting plain white light at the other side of the map.
Putting lightprecision on 64 or even 128 wouldn't be a bad thing for this map, as it would decrease the file-size a lot.
Detailing
There seems to be plenty of detail on the map, but I think you added just too much of it (as the wtr-count shows). Just keep details simple, yet effective.
Clipping/Noclipping
This is something that could be improved greatly. Player are able to leave the playgrounds and watch all the happening from the border. This isn't a good thing for a map which is focused on teamplay, as other players need their teammates to win.
Flow
The flow seems to be ok, but at some places, your just getting force to trickjump. This shouldn't be done like that (as there isn't any hint you should trickjump). Make sure players are able to access every room on 2 ways and every platform on at least 1 proper way. This creates a less predictable gameplay, as players can't be sure the opponent is navigating to a certain spot after the opponent left the area in which they were standing.
Also, the idea of being in a castle isn't bad, but don't over-size it. Players aren't willing to take 6 steep and boring ramps (which are decreasing the flow badly, as you get very vulnerable taking one of them just because it slows you down immensely) before entering a floor below the flag and realising they can only reach the flag when they would be on top of the castle.
Just make sure there are at least 2 direct ways to the flag and keep the castle simple. Players should be able to get the flag quickly and leave fast also.
Gameplay
As I've already told at the flow, the bases are way too complex. Just delete like 6 floors and only stick to 4 floors each base. That would increase the framerate for players, keeping the details being less repeated and improving the flow, but also the gameplay.
The ammount of playerstarts is having an odd number, while both bases should have an equal amount of playerstarts (to keep it more fair).
There are rooms which have a lot of pickups, while others only have a very few. Be sure to fix that.
Overall
So let's summarize this:
- Only keep at maximum 4 floors on each base (I would recommend 3, don't keep any floors between the bridge and the main ground (floor 1), keep the floor which the flag is positioned on (floor 2) and keep a top of the castle (floor 3)). This is just to improve the flow, gameplay and geometry.
- Delete all the glass in windows, platforms, etc and also delete the second heap of diagonal bars in floors. This is also just to improve the geometry.
- Fix the colour of the lighting (or the light-sources).
- Add clip so players can't leave the playground.
On the first eye, the map looks pretty good, but after checking again, it still needs to be improved greatly. Still some nice piece of work though. I'll rate 5/10 for now.
