Sport games usually don't hold during the years, and the times have not been kind to Nintendo's Tennis.
To be fair, it's a fairly decent title for an NES game. Was also a learning experience for better Nintendo games like Mario Tennis.
However besides a few extra modes of speed/difficulty, and the options for double matches, there's really nothing left to chew on.
It's probably a really good game for it's time, but honestly today it can't hold a candle to even Wii Sports' Tennis Mini-game.
Score: 3 out of 10
