Unfortunate that the hate Mario’s Tennis; I personally think it’s a great game. I actually am a huge Mario Tennis series fanatic. The Virtual Boy version was the first game in the series, and that’s quite special as the series is still popular today.
This is a pretty bare bones review. Sure it’s kind of a basic game, but it plays way better than this dude leads on. It’s not any harder to get used to than Mario Tennis on the GBC.
