I unfortunately don't have much time to play games.
I've tried Zork a few times, but I always get stuck near some clearing, and I don't know where to go. Basically at the start.
Anyway, curiosity combined with imagination, yeah, could be fun.
Main reason I haven't tried it is pretty stupid. I don't know how to save and reset, otherwise Zork is also on our SDF pubnix. But I also didn't really go out looking. You can try it without sign-up on telehack.com. Also, why the hell can't I run telnet (freezes or takes long time to respond) on Arch + KDE in terminal emulator (I tried 2), but it works in TTY?
