ninja you dont understand, tremulous is free so developers cant get money for this oldie so it isnt their job, it isnt their first thing. AAA Games are not assholes, you may be if you can't figure it out. They offer PAYMENT for working on T2. That means it'll be made.
People you are talking here about licenses, what about you go sue them? Let's see who will win. Less talking, more doing if you are so sure they're fking copyright stuff up. Please, go on, I want it to see.
because every project that has been cancelled never paid for work, right?
do you see the flaw in your logic?
you are right, tremulous is free. AAA would do much better going the UV route, and USING NOTHING FROM TREMULOUS, NOT EVEN THE NAME (though in UV's case, they are adapting and modifying tremulous' source code into openwoolf, and building on top of it) using tremulous' free and open sourced material to make a commercial project is wrong in my opinion, and makes those who attempt to do so assoles of the magnitude of those who took nexuiz commercial. and how that turned out is quite publicly visible.
as for lawsuits, i could not sue even if i wanted to. i am not a copyright holder in this matter. this does not mean that i cannot call plagiarizing assholes out on their copyright violation.
lets go over it one more time, in tl;DR format.
using original assets and name = good
using work derivative of assets in trem without proper attribution, and tremulous name = bad
tthey could do a 1:1 duplication of the gameplay, provided it is in a properly licensed engine, with their own code. that is good.
