Rockstar has top-selling 2010 title

Red dead seller

Rockstar Games's Red Dead Redemption is the best-selling game of 2010 so far, but with several months to go can it hang on to number one?

IGN has a list of the US top 10 best-selling games of the year so far as enumerated by research firm NPD Group and it's a surprising squad.

Although 2010 release Red Dead Redemption tops the list, the next two games--New Super Mario Bros. Wii and Call of Duty: Modern Warfare 2--debuted last November.

Red Dead Redemption is certain to stay on the list come year's end, but watch for Halo: Reach and Call of Duty: Black Ops to give it a run for its money.
