I don't normally sit down to play sports games, but very few managed to hook me quite like Captain Tsubasa Vol. II: Super Striker. This is easily my favorite sports game on the Famicom, easy to play and understand but hard to master. Even when you do lose against the computer you still level up and have a slightly better chance at winning the next game so there is incentive to keep on playing and eventually beat the game. I couldn't recommend this more than enough.
