If you haven't seen it already, there's a new game announced at E3 called Quake Champions. Video is here:
On the outside it's pretty obvious that it's going to be a high definition Quake 3 reboot of some sort, complete with Ranger and Visor already present. I already know what some people are going to ask, and the answer at this time has to be "No". Wirehead currently has no plans nor inclination to look at switching over to Quake Champions for Generations Arena. Why? There are several reasons.
First, not enough is known about the game. We've seen some characters and a few weapons. We have not seen all minimum characters necessary to round out the Generations set. Doom, Sarge, and Grunt would have to be present, and our familiar characters so far are only Visor and a Quakeguy. Due to intellectual property concerns, these characters would have to be present in able to create their character classes properly.
Second, there's no guarantee the game will even support mods or private servers. If it can't be modded then it can't be modded. Something like Snapmap wouldn't be enough. It would require full mod support that's been present in previous Id titles. Private server support would also be a must, as there's no guarantee Id or Bethesda would host mods. There's no point in modding if people don't have servers to play on.
Third, Wirehead only has firm permission to create Generations Arena for Quake 3 Arena. We do not know if such permission would extend to another game or if we would have to go through the entire contact process again with Id. Besides that, it may be entirely possible that Quake Champions ends up with a Generations-ish weapon set for various characters, which would defeat the purpose of us trying such a thing anyway.
Lastly, our team has shrunk to pretty much myself and a few beta testers. We would need to rebuild a full studio-sized team to undertake work on just the media assets alone, not to mention the amount of program code that would need to be rewritten assuming that everything else fell into place. There's no way I could do this by myself, and assembling a new team would be difficult.
As it stands, Generations Arena will continue development for Q3A. It will be completed for Q3A. Beyond that I cannot say anything more than I already have until more is learned, though discussion, as always, is welcome.
