Good quiz! Here's my 2-class, 260-loc. http://www.d10.karoo.net/ruby/quiz/49/lisp_game.rb Major features: 1) No documentation. 2) Scottish spelling of whisky. 3) '-cheat' command line option so that it plays itself and saves you a whole bunch of time/typos. 4) 'weld bucket chain' == 'weld chain bucket' config option. 5) 'weld frog JEG_II' bug fixed (was jumping to "YOU WIN"). Apart from those, it's just as user-hostile as the original. ;-) Cheers, daz
