Back in middle school I would play games like bowman, kitten cannon, sniper assassin, etc. On sites like addictinggames.com, or crazymonkeygames.com.
I know these games would have ads run on them, which I assume was profitable for the developer. Especially titles like those that probably have 8 figure play-stats across the internet.
I was wondering if anyone has any experience with this market, and could provide some insight as to how it is doing now, and what is used to make these games: Is it financially worth developing a browser game? Do I have to use flash to be accepted on these sites?
