Theres a difference between liking and fanboyism.
I used to drool over Halo; I guess its when something is good enough to win over your mind against all the competition, and people get convinced it is the best thing ever. Plus the rate of really, really good games released is pretty small, so I guess good games aren't hard to idolize.
when halo 3 came out
i drooled over it.
then i realized halo 2 was better
when gtaiv came out
i drooled over it, then i got gta sa and realized that was way better.
when the gtaiv:EoLC came out.
i drooled over it, and still do.
ima drool over epic mickey when that comes out too
