Wait...who says FPSs don't have replay value? I think there's few rather large franchises of fans who'd beg to differ.[/spoiler]
Agreed!
I would like to submit Metroid Prime to the Argument that FPSs can have a HUGE replay Value, biased solely on Single payer campaign.
And id even replay MW2 if i had it, simply because i thought it was fun.
And fun is subjective.
Honestly, I play through almost any game I enjoy more than once. When I'm playing for the story, I just wait longer before I replay, because it's more like rereading a favorite book.
I agree with this too.
