basically, everyone wants to play something new, but if those individuals don't like how the game is made and wish it were more interesting, and since it's unlikely that the developers will listen to them or even want to fix anything, this hopeless situation forces them to "sit and grumble."

and by the way, there are many more "dissatisfied individuals" or simply those who might say "Heroes 5 is just an okay game; I expected more. It's disappointing," than there are those who will say "Heroes 5 is the best game ever; you can play it for days and nights; I like everything about it."
