Luckily, most of the "exclusives" are cheap ripoffs of non-exclusives or just plain suck. Halo falls into the latter category. It's popular because console gamers simply don't know any better.
Or because they have a different opinion than you >_>
Console'rs may love Halo, but that's only because they quite literally don't know any better.
Hope you're not lonely up there on your pedestal.
