After recently playing Portal I have decided to write about the multiplayer and how it may play into marketing. The first feature I noticed while playing multiplayer that I found interesting was the the ability to play multiplayer both online and with another person in the room. I've noticed that this feature is disappearing from many of the big title games that appear on the 360 and PS3 sysetems. Since the original Portal did not contain multi-player the inclusion of multi-player in Portal could prove helpful in its marketing. While the original was fun it grew boting if you were simply being a spectator.
