Is the 90s compedium still viable? I've dug the Polish version up as a collection item but I have a friend that doesn't speak English so I thought I could lend it to him to read since the newest editions don't get translated. I started playing only a few years ago so I'm not sure if CGL changed something when compared to the old rules, but I heard they're mostly intanct and all that changed is that new equipment was added for the new eras.
