If I were to do it in Haskell again, I would try to learn more about FRP (Functional Reactive Programming) and see if that improves things in terms of state.<div><br></div><div>Ruby is my favorite imperative language, so I would certainly recommend it for game development. It would likely be much easier in Ruby, but perhaps a little slower. My experience with Ruby on Rails has been that it is always a little slower than I wish it were :)</div><div><br></div><div>-- Duane</div><div><br><div><div>On May 3, 2009, at 4:48 PM, Daryoush Mehrtash wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">I noticed that Chipmunk also has a Ruby interface.
