Sega Superstars Tennis is an inconsistent tennis game that has you laugh one time and yell the other.
AI-
The AI in this game is atrocious. One moment you'll whip them like cream and the next round they'll play like tennis pros and smoked you in four shots. This inconsistent Ai is the most frustrating thing on earth and you'll find yourself slamming the controller on the ground many times.
Gameplay-
The tennis in Sega Superstars Tennis is decent at best. The superstar moves are also inconsistent you'll notice that when you do one the ball goes directly to the opponent and when the AI does one it'll go in the complete opposite direction of you, and they'll go off screen to hit one of yours which is extremely irritating. Maybe the most annoying thing about this game is making you do pointless minigames to unlock stuff.
Graphics-
Not much to comment on. The enviroments look great though, as do most of the characters. Some of the sonic brand characters look kinda of weird like tails and amy. The courts are great and really creative and are just fun to play in because they all have a different atmosphere.
Overall this game is inconsistent and annoying and easily the most frustrating game on the planet earth. Don't buy this game unless you can find it for under $20 bucks...I did.
