I used to play Nexuiz 1.5 quite a bit, mostly on the (now closed) Stormix and Fragtory servers. I'm not too happy with 2.0, for two critical reasons. The first is that I hate the new movement physics compared to the original fast-paced style that set Nexuiz apart from other FPSs. I miss the slow acceleration / high velocity settings - although I do feel that at least the weapons are more balanced now. The other major problem is that there are no American servers anymore - except for All Out War, whose non-standard configuration has always made me a little dizzy, and a couple of ladder servers.
I think it's a real shame that a game I used to have so much fun with has died with a fizzle. If anyone happens to have handy a configuration file to make 2.0 movement feel like 1.5, I'd probably like to use that for lan games. Increasing sv_maxspeed and sv_maxairspeed by 50 or 100, and decreasing sv_airaccelerate a little seems to make a huge difference - are there any other settings I should look at?
Unless / until a low lag server opens up, I'll probably still play a few minutes on a European server every now and then, but I get the feeling that there's no going back to the good old days of 1.5 on Fragtory.
