Purchased Mario Tennis Ace. I hear how this game wasn't great upon first release, But I must say I'm pretty impressed. Graphics look great, gameplay is great for the most part. There seems a degree of games during Doubles matches, where the Ai will just continually hit the ball across court to each other.
Difficulty seems decent too. Me and my partner played Doubles vs two large characters (bowser and plant). I believe we was playing on Pro and we lost 6-4. Due to the size they did keep getting in each others way too.
Id like to have had the ability to play real tennis, can't seem to play 3 or 5 sets. Best seems to be 6 games and 1 set. Can't select CPU v CPU matches.
So much fun just playing doubles though.
