I'm going to try to learn RoR but before i start to do that I'm going to try to learn some Ruby for a better understanding on how RoR is working.

I have Java and C++ experience so object oriented programming is nothing new. Ive found many useful tutorials and i find the best way to learn is to make a bigger more advanced program/game.

That comes to my question. Does anyone have any good suggestion of some good programs/games to make to learn Ruby. To make it easier I don't wont the program/game to use any graphics because i wont use that knowledge later.

anything that takes your fancy... Be creative, use your imagination.
