Half Life wins 7-6.
Super Mario World (7)
VS.
The Legend of Zelda (10)
I'm going to be leaving GR for a few weeks to get some things straightened out that are more important, so if you don't see me on AIM, that's the reason. I'll need somebody else to take care of the showdown until I come back, so if you're able to post the new showdown everyday sometime inbetween 5:00-7:00 PM Pacific (8-10 Eastern) please do so. The bracket can, of course, be found in the first post in the topic. Just make sure 24 hours pass inbetween each match at least (barring a big blowout, in which case an hour or two less won't hurt). And if you think you won't be able to do it anymore/for one day, pass it on to somebody else. Don't worry about updating the bracket, I will update it when I get back, or if I'm unable to be back fully in the next 3 weeks will make sure I log on around that time to update so the bracket is readable.
I vote Super Mario World.
May the best game win.
