All the features are nice, TV Guide worked (note that browsing and setting recording preferences is very SLOW), BUT when the TV Guide is downloading (all the time) or you are recording / playing from the hard drive you constantly hear a grinding sound from the hard drive. These guys must have used a cheap hard drive or something. I have the Amazon return slip on my desk......

I am a huge fan of the Tomb Raider series, and have played all five other games on my PC. I love them. I was so excited to get this one, and sooooo disappointed with the quality. Glitchy glitchy glitchy. Do not buy this game. The controls are terrible. While all other 5 games play out smoothly, this one is slow, stalls, goes blank some times, and takes minutes to load to new chapters. Now I don't have a fancy schmancy computer, but I have been able to play all the other games on it just fine without any hitch. This is just crap. It makes me feel like I have to go buy a $2000 computer just to be able to play this $30 game! It probably runs better on a PS 2, so if you have one of those don't bother with the PC version. Thanks a lot Eidos, I totally wasted time and money and am warning future buyers to BEWARE!

I couldn't wait to read the first of the Foundation novels, having got such great reviews, and having heard that it's been such an inspiration to so many other sci-fi authors. But I could barely finish it. The book is flat-out boring. There is no action, choosing rather to focus mostly on matters of political intrigue. If you like watching CSPAN, then you'll love this book.There is also no continuity of storyline or characters. The book constantly jumps ahead in time right about the time you've wrapped your head around the current characters and plot.It's like a set of boring short stories, loosely stitched together with an single underlying theme.
