-Balls sometimes go invisible.
-AI players rarely miss.
Basically ISC has everything you need for a snooker game but there could have been much, much more. Let's start with the gameplay. The physics are quite realistic and as you'd expect. After a few minutes of playing you will realise that the game doesn't offer much for beginners except for a small practice mode. You'll find it hard to win your first match because the computer players are so accourate with their shots. The graphics are acceptable but not great and has one major problem of some of the balls becoming invisible. The only sound in the game is the sound of a ball being potted, hit and the main menu music. Lastly all the players in the game are fictional and so are the venues and tournaments. The main thing though is that it plays ok.
