Nice, big fan of browser based multiplayer stuff. I think there's so much potential now to make some crazy browser based games given current state of web apps.
So the OP said that there was "a team in Traansylvania making it a legacy codebase". The literal meaning is that there is a team of developers in a foreign country being paid less to do the same job. The other guy said it was offensive because he's implying something similar. He's also working in a foreign country for a US business. More of a joke about being offended. At least that's how I'm reading it.
