GameSpot is a website that provides video gaming news, previews as well as downloads and reviews. Play N Trade on the other hand is a retailer that deals in video game as well as entertainment software. In my opinion, Play N Trade offers better deal and sales promotion because they pioneered in in-store tournaments and have a big assortment of classic games.

Gamestop is more successful i know because there were 2 play n trade were i live and they both got shut down but i have never seen a gamestop shut down bottom line gamestop is better and they have the best deals.
