They seem attractive and you could get a lot of people to play your games etc, but the high bandwidth costs, and low number of clicks and entertainment clicks at that even (low cpc) just force me to think otherwise. So, the question is, are arcade sites really worth it? imo they aren't worth the trouble. IT
If you are wanting to make money its not the route to go. I ran one a while back and enjoyed every minute of it. I can just say its probably not worth the effort if its about $ to you.
high bandwith will cost you alot,u will get $$ no worries but I dont think this would be worthed to your effort in handling the site.
