I love Dick Tracy! I still need to snag the bluray. Have you played the Genesis version? Developed by the Shinobi team, it plays very similarly, trading up horses for cars and including the machine gun mechanic.
I think that was one of my first Mega Drive games, it was ROCK HARD. Even when we bought it the lady was talking to my dad and my dad said "Is this game good?". The lady looked at 5 year old me and asked "Is he good?". The game was so much fun even though it was tough.
I came back to it years and years later as an adult thinking, 'hey here's that game that was tough when I was a kid' and guess what, it's still ridiculously hard. Great game though. The music is an underrated OST especially!!
Also, I bought this game in Australia when prices were outrageous for video games. I think it was about $125 or something.
On topic: Last thing I spent money on... Groceries.. How exciting! A dozen eggs, salad, steaks and chicken breast. I'm trying to tone up and have been lifting weights/changing my diet. Seems to be going well so far.
