We were talking about this on irc just now.
Here's how I see it.
I played qw for a few years then took a few years break. Then I tried nexuiz. I felt that the movement was horrible and unresponsive and I gave up after a couple weeks. I mean, I liked it and it was fun but I didn't see how one could play this game seriously because of the movement. Then a couple months later I decided to give a try again, met some cool people and kept playing. Eventually, I got better with Nexuiz movement and I realized that the physics/movement didn't suck, it was me that sucked at it. I've (only) been playing for 1.5 years I think and I still don't feel that comfortable with the physics, but I still make progress every time I play and I find them amazing and complex now. Just like someone who never played a fps game playing cpma for the first time would feel like they can't move well, it takes a long time to learn.
Basically, what I am saying is that I understand how new players coming from other games feel when they try Nexuiz. I did the same thing you did when I started playing, I asked around about making changes to the physics so that they would be more like the game I used to play and there is nothing wrong with that. And at least you did it in a diplomatic way compared to a lot of other players trying out Nexuiz. Obviously, the learning curve would be easier since most fast paced fps games (ie: qw/cpma/wsw) have a similar movement system and I can see how it would make sense that Nexuiz use that system too. But honestly, since I still make progress with movement, that I still find ways to accelerate faster (without using weapons), turn corners tighter, etc. every time I play after more than a year that means nexuiz movement is very complex and hard to master. Hell, everyone seems to progress a lot these days, I remember when I started playing I think there was like 1 or 2 players that I knew of that would let go of +forward when bunnyhopping and now everyone is learning how to move that way and combining it with regular bunnyhopping to not slow down as much as possible. You discover a lot of details about the physics, the right angles, the friction, the speed at which you need to turn you mouse, everything. I find all of this very exciting. Nowadays it feels like I move a lot like I did in qw, the angles and air control are different but it's very similar in a lot of ways.
So I find it kind of sad when someone comes to a server and says "this game is stupid, why is it not like that-other-game" and then leaves. So I appreciate your approach to suggest this. Personally I would like it to have it as an option in Nexuiz. I do not know if I would use cpma physics, but I'm all of more options.
