The Third Round: (*easy*)

spin the choice :D

text editor

a text editor wouldnt that qualify as hard? im thinking of something along the lines of VI and that would be quite involved...

Card game sounds fun. Like poker or blackjack. I made it in BASIC once, the shuffling algorithm will probably be a bit harder without that good old goto though.

how about a text file compressor..

I'd say slot machine...

A small rpg.

I take it by "very small" you mean it could also be an engine, instead of a playing version.... right?

I say a "Calculator", If not, "Obfuscated C Code". Calculator will make us brush up our maths and obfuscated C is real fun :)

obfuscated's are always fun. Let's do that.
