The agreement between EA and Hasbro has brought us Wii games like Nerf N-Strike (with its awesome Nerf gun peripheral) and Family Game Night. The line of games, across multiple platforms, has just sold over two million total copies, with the Wii games contributing significantly to that total.
Nerf N-Strike has hit #10 on NPD's Wii sales chart since its October release, according to Gamasutra. Family Game Night and Monopoly Here and Now had solid, but unspecified, launch sales as well, and "continue to build momentum," according to EA's Chip Lange.
Really, we're pleased with anything that encourages the combination of Nerf guns with any hobby.
