I would highly recommend this as a really enjoyable watch. Mark Lesser gives a few interesting insights into the programming of the game such as passing attributes and how one-timers were done. Also, interesting that more animations were done for fighting in 94 such as pulling jerseys over heads, before fighting had to be ripped out. That I would have loved to see!
My only complaint is not enough about Jim Simmons apart from a few mentions (for us that think NHL93 is better). It's also interesting that Lesser said Jim Simmons dumped the code on him and he didn't have time to start from scratch (like he wanted to) but only developed the code. Over the years he said he ripped out more and more of the code which may explain why the game went downhill after 94. If it ain't broke don't fix it.
It kind of leaves me wondering if maybe Simmons had continued developing the game how good it could have been?
