"The other three categories, Aerobics, Training Plus, Balance Games offer nothing new."

Seconded. Eternal Darkness has stood the test of time a lot more successfully and would be better viewing material.

I'm pleased with the inclusion of elements such as alternate paths and ranking/upgrade interface. The main issue with this style of game is commonly the length, but you've assured me that there are enough reasons to replay levels, which should extend the number of hours I could put into Extraction. Cheers.
