B is definitely filled with good NES games. Burgertime (a port, but still good), Battletoads (a classic), Bubble Bobble (another port), and many more. There are also some tragically horrible movie games, Blues Brothers and Back to the Future. However, I'm going to step a bit out of my bubble and talk about my favourite sports game, Blades of Steel.
In my opinion, Blades of Steel has a great fun factor. There are some extra touches that make it stand out for me, for example how the players skate in a pattern around the rink before the beginning of the game. I was actually at a hockey game recently watching the players skate around, thinking, "This is just like Blades of Steel!". That's how much of a dork I am. Also, you can sometimes see a zamboni driving by in the background while you pick your teams. Another great touch is the announcer. I always appreciate some good voice clips on a NES cart.
Since way-back-when, I've played several newer hockey games, but I never seem to enjoy them as much. I think that the newer games almost suffer from too much sophistication. I don't want to pick my lines, I don't want to make trades, I don't want to draft players, I don't want to learn the buttons for each kind of physical aggression, I just want to play some hockey with my favourite teams, dammit! Every once and again, I need to punch something. Blades of steel lets me do both of these things. With multiple difficulty levels, I can enjoy creaming Toronto over and over again, or I can try to challenge myself, depending on my mood. Everyone who has ever read "The Hockey Sweater" will probably enjoy destroying the Maple Leafs 20-0 playing as the Canadiens.
This brings me to the last thing I really love about Blades of Steel, the bright 80's teams. It adds so much to the classic, nostalgic feel. And, without having to pick your lineups and choose your players, you can imagine that anyone you want is playing on your team. If you'll excuse me, I'm going to go pit my team of Gretzky clones against the worrrlllddd!
