Yeah, I suppose you're right in that sense, with the top players being a lot more unforgiving, it's just that the individual shots were sometimes a bit ridiculous, even by professional standards!
Did you play WCS 2004? I think that one was probably the best in the series, I enjoyed it a lot anyway

.
Watching the trailer again, I can't believe they still havn't sorted out the animations - players getting up half way through the shots, not cueing straight... seriously?...
Even players at a very low level don't do either of those things - you can go to your local snooker hall and see better technique than the animations in WSC for the top professionals.
Not only should the animations be realistic, they should be varied and have different players signature styles, such as Marco Fu's "point and hit" action, or Stephen Lee's super-smooth cueing. I thought that would pretty much be a priority for them, but the animations look untouched...
