"we’ve learned that the successful teams...build on mature (read: “old, creaky”) technologies, because you want to spend time making the game fun, not trying to get the latest and greatest development tool to work."<p>That, rather painfully, makes a lot of sense. We're 18 months into building an HTML5 game (<a href="http://warsocial.com" rel="nofollow">http://warsocial.com</a>) using rails, node.js, redis, angular.js and a bunch of other 'latest and greatest' technologies. We probably could have gotten where we are now in a couple months if we had just gone with Flash + PHP or something, and put the rest of our time into making the game better.
