Although I love to make fun of Sega, it's really just a byproduct of two things:
1) It's just so damn EASY when they keep doing incredibly stupid shit
2) The irrational Sega love over at OA makes it easy to rile that crowd up
...I will admit to being a Sega fanboy in the early stages of my videogame life. We're talking Master System and Genny, here. In retrospect I can admit that overall the SNES was superior, but MAN did I love my Genny back in the day.
Since the first couple years of the Genesis, though, Sega has pretty much consistently done EVERYTHING wrong, except for the Dreamcast launch and first year or two. But by that point no one gave a shit anymore. Sega will never recover from going 3rd party, and it's a damn shame. Honestly, though, they deserve to die for Shenmue alone. Christ that game is fucking awful.
