"I hate people that say it is so horrible that they didn't make a completely new engine. The regular engine works, and quite well. They used the original engine so they could spend time looking back and thinking what didn't work well with it and fix it. If they made a completely new engine like all the haters say, it would have a whole new set of problems to deal with."
