First off, do you really have to put all those emoticons there? Second, I remember hearing the name Halo and thinking "What a girlish name, that game must suck." Then when I went to a friend's house, I played it and realized that "Halo" stood for the best game I've ever played.
I don't really remember how I first heard about it. Maybe I just caught little snippets of it at school, then my older brother bought it at Newberry Comics, it was the first game we got (other than the Jet Set Radio Future/Sega GT 2002 hybrid disk it came with). I've been hooked ever since.
