Oh! I don’t believe that anyone still remembers this great project! Thank you for thinking of csDoom!
It was my first project when programming was just my hobby. I was 17 years old when I developed it. 21 years have passed since then… csDoom (client/server Doom) was the first modification of “Doom II”, which allowed people to play the game over the Internet. I still remember the details of how I developed it and how I discussed some topics with John Carmack – the God of the 3D industry and the grandfather of all 3D games we enjoy now.
Yeah, snatch me while you can!
