Hickory: You would never ask a stranger to pick your own clothes or car, so why ask them to choose whether you like a game or not? Go for it.
Flawed analogy. The situation is more akin to reading reviews for a shirt or car prior to buying. Shirts are purely functional with minor fashion value, and an in person inspection prior to buying beats a review unless the review points out a latent defect. As for cars, you better believe I'd be checking reviews to make sure that the bloody thing starts, gets the mileage it claims, and flat out functions as promised before buying it, especially since me inspecting it without assistance is not likely to reveal any defects.
Games are more like cars than shirts in the fixed version of your analogy. Especially on PC, one is not able to do a physical inspection prior to buying, and the amount of money and time at stake, while not as much as with a car, is relatively high to the point that buying merely to "try it out" is akin to playing Russian Roulette with one's wallet and spare time.
