Yeah, they don't make them like they used to. Don't get me wrong, I do love the current crop of games, but there's just something about the classics that always pulls me back.
Yeah the engines are impressive. My duties keep me in the terminal/ yard so I rarely get to ride in them except for some company events but even driving through the yard you realize how massive and powerful they are when you only a few feet from them.
Thanks for the interest!
