This is not a game I can honestly recommend with a clear conscience, although people looking for a Snooker simulation on Steam are going to find their options sorely limited; this is in fact the only one, but there are so many things that don't feel right with this game.
The AI difficulty can vary wildly within the same match, and even within the same frame, going from missing shots you'd think were unmissable to clearing the table unless you snooker your opponent on the break. The AI has no concept of shot selection either - in one example, the computer opponent had potted a red and ended up in the jaws of the middle pocket, completely unable to see pink and black. He them promptly nominated black (despite having an easy blue he could drop in to the opposite middle) and proceeded to play the cue ball directly into the jaw of the middle pocket, sending it careering around the table and missing everything. This happened 3 times in a row, at which point I was awarded the frame. Laughably bad.
Michaela Tabb, bless her heart. She's a good referee and a likable character on the Snooker and Pool circuit, but there's no visual representation of her in-game at all; she's been reduced to a disembodied voice with about as much emotion in her tone as GLaDOS in Portal. In some instances, the game doesn't even get the scores right - on more than one occasion, I've potted a red, followed by a pink (for a break of 7), only for the game to proudly announce that I'm on a break of 6. The only thing stopping poor Michaela from turning in her grave is that she isn't actually dead.
Sending the cue-ball in-off is a common occurrence, but one that seemingly happens at random, completely irrespective of how careful or otherwise you're playing. There is no consistency with shot power, with a 100% power shot sending the cue ball all the way around the table twice, but a 40% power shot is rarely enough to even pot the black off its spot.
Animations of the crowd clapping are horribly and obviously looped, the player character is never seen and has no character model, so you can forget about character customisation aside from the name, and the opposing player is only ever seen sat down at the side of the table while you make your break. Obviously it was too much to ask to animate a model of someone walking around a snooker table and playing a shot.
If you want a good snooker game on the PC, avoid this and buy Virtual Pool 4, which has a fantastic snooker game mode.
