Finally I leave you with some food for thought about dealing with Elitism in todays gaming world. I'm sure I could have made an entirely different post for this topic, but my purpose is to not debate the issue, but to bring a mature outlook to the conversation. If these type of opinions don't intrest you then by all means please don't waste your time checking out the video. But if your like me and enjoy mature intelligent conversations then you won't be disappointed.
