Vlambeer founders Jan Nijman and Rami Ismail revealed at their GDC Europe presentation that Ridiculous Fishing has sold 300,000 copies, according to Joystiq. At $3 a copy, that's $900,000 in total sales. So close to $1 million! This is really great news considering the hell Vlambeer had to go through after their game was cloned by an asshole.
Funny enough, Ridiculous Fishing was almost a freemium game. The duo considered offering the game for free, and then selling stuff like a $1,000 in-game boat. Players would have been able to see their friends' boats off in the background, with the thinking that players would be tempted to collect all the cool boats they saw. Thankfully they went with charging $3 for a full game over nickel-and-diming players.
