Yeah, title says it all. What video games were super hyped, but yet you personally don't feel that they live up to that hype?
I would say first-person shooters in general. I can see why people like them, however, they just aren’t really my kind of game, especially the real-life military ones like Call of Duty. Give me platformers & RPGs any day over shooters.
I also think World of Warcraft is overrated. The gameplay is fun, the storyline is very epic, and I'm looking forward to the new Cataclysm revamp. But, the game has a number of annoying gimmicks in it, like the Alliance vs Horde war & vehicle combat. The game doesn't have player houses & guild halls, nor a really memorable professions/crafting system. A few of the races & characters, like Blood Elves and King Varian Wrynn, are shooting near the top of my "most hated characters" list. Sadly, I think that I prefer the Shaman feel of the Horde, but lore-wise, my heart lies with the “underdog” Alliance races & characters. The ten classes are really well put together, and the game does have a solid assortment of holiday events, but there are other MMOs that deserve some love as well (EQ2, FF11, etc.).
