Uh, why? Now that I think of it, I too would like to try out 1.0, since the earliest I've played is 2.5. Screw it though, I'll go get a torrent if everyone here's gonna be like this about it. If I find a download that works, I'll PM you War_Hero.
Im pretty sure that anything from 1.8 and below never reached the public.
Also, im not fond of you using torrents to find Toribash. You dont know what shit people add into a torrent.
TB1.9 is basically the same as it is now, it still plays the same there is just more features and some graphical improvements like anti aliasing and mods
