From Xbox Evolved:
"First-person shooters have gone from being an unknown, yet very popular, variable in the 1990's to the most dominant genre in gaming today with the exception of maybe sports titles. Every month now, it seems like we get another two or three. They have certainly supplanted RPG's as the most prolific gaming genre as the industry has gone more mainstream, especially in this decade. Games like Halo, Half-Life, Call of Duty, and many other wannabe greats have made their stake in the industry. However, many of them released today have a problem that seems to be growing and for the life of me, I cannot understand why. This is what I call the "silent protagonist syndrome". "
