Yes, well, everyone knows of Kongregate.
Also, Kongregate is different in that it is a portal for games mostly by 3rd party publishers rather than a host for games that are all programmed in-house.
Also, the few games on Blurst.com are unique and largely based on physics instead of being just a few more "tower defense" clones.
Don't get me wrong-- I love Kongregate. It's just that it's a different sort of site.
