WTMG's Leo Faria: "AO International Tennis isn't exactly a bad tennis game, but it's far from being the best one I've ever played. It has some interesting ideas, but it also suffers from clunky controls and an overall lack of licensed players."
Pure PlayStation: AO International Tennis is not a terrible game, it's just not a very good one. It has most of the ingredients to make for a decent tennis experience, but it just hasn't been cooked well enough.
Hardcore tennis fans will get the most out of AOIT, so if you're just a casual follower who refers to Murray as British when he wins and Scottish when he loses, this isn't for you.
MonsterVine: "AO International Tennis captures the war of attrition that makes the sport tense and arduous. But the entire experience, both the ups and downs, felt stale after some time. "
XBA says: Does this one serve up a smash hit or a deuce?
