text: how feasible is it to use "ruby" language to write the model (not rendering engine) for a video game? i know ruby is much slower than c++ and even java for most operations, but i've fallen in love with the language, and would like to write at least a game's model code (game logic) in ruby, and perhaps use an existing engine for rendering.  i was wondering if i should just stay away from this idea altogether because of the poor benchmarks i've seen for things like recursion. as you already know ruby is a interpreted language & as a result it is very slow for something like game programming. i would recommend you to use ruby for the game logic only if you have a very less processor and graphics intensive game in mind. like say tic-tac-toe or chess(if slow response is ok). if your making a very realtime game then i would recommend u stick to c, c++, java...
