This is a topic I'm starting from my own choice as I thought it would be helpful to bring it up at this point, so I hope that's ok even if I may not know some of the plans the developers have. It seems that the Nexuiz SVN is slowly getting closer to being released as the latest official version of the game, probably won't be longer then a few more months. A lot has been added and modified since the latest release, but there's still one thing that seems to be missing and pretty much needed: More maps.
The game still has very few maps in my opinion, and from what I seen it could really use some extra maps for different gametypes right now. For DM there is a reasonable amount, although for other gametypes more maps would highly be required. CTF for example only has 3 maps in the SVN, which I think is really not a good thing considering what a loved and common gametype that is. Another reason is that the SVN has new map features as well, like the new pointparticles system for custom particle generators and an optimized map compiling system with some new features in it.
Also, as I had previously mentioned on IRC, I believe the game could use some maps with terrain as well at this point. ONS-Reborn is the only official map with terrain but I seen a few beautiful maps containing heightmap-generated terrain in outdoor environments (one was some map in a temple, with open textured terrain on the outside and a beautiful waterfall in a corner). Outdoor maps would be very welcome in my opinion, because in most of the maps from the current game the action takes place in either a small dark facility or castle, and that's pretty much the atmosphere around the current levels. I think we need at least two or three maps with beautiful outdoor environments, green grass and sunny outdoors to brake the monotonic cycle of closed castles and facilities, and have some nice outdoor maps like the ones from the UT2kX series. So far terrain generated with stuff like EasyGen seems pretty useful and is also great with the performance since all the insides are caulked.
Anyway the idea of this topic is to ask mappers who have made good quality maps (with or without terrain or other features) if they are willing to give their work for the SVN and have their maps officially put in the game as long as the developers want them as well. I'm not sure what kinds of maps the team is looking for, but certainly more maps overall are needed. I tried making this map a month ago myself, precisely with the intention of proposing it for the SVN although I couldn't make it as good as I wanted in order to do that. So if you're willing to propose a good map you made for the game, post here and include some screenshots and info of your map(s) as well if you have any. This should make it much easier for the devs to decide what maps they wish to add in the game at a certain point if any.
