I've not trusted what reviewers say for a good while now any way.
It's all very well and good them doing it for a living but we're not all the same. Everyone loved GTA: San Andreas but I didn't. Lots of people's opinions differ, that's why I love having Demos. While they don't give you a full example of what's going on, it gives you a taster so you can say. 'Hey, I might enjoy this game.'
