Sometimes I forget the wiki even exists, to be completely honest.
I just don't find it useful. I come to Giant Bomb almost exclusively for video and audio content.
Yeah, harsh but true. I pay my subscription just because I want to support the Bombcast and some of the video content. I'd prefer they ditched the Wiki (I mean I usually Google the game I want to know about and that usually leads me to Wikipedia) and wrote some more articles. I get so much of my news from places like Joystiq and IGN and like the longer features from Kill Screen. They need writers to write stories.
The Wiki is filled with conjecture and has a strong American bias... I've made changes in the past about PAL releases and had them either rolled in the US release or deleted entirely. For example - Sonic on the Master System is an entirely different game from the Mega Drive version, but the 16-bit and 8-bit versions were merged. They have one level in common. But hey, the Master System wasn't big in America so it doesn't matter. Sounds petty I know, but if you don't care about acurrately recording the history of video games what's the fucking point in this who section of the site?
tl;dr -- Ditch the Wiki, write more stories (and news), focus on the site's strengths (Bombcast, Quick Looks, other videos). Or keep it. Whatever haha
