SEGA's latest — perhaps last — Wii game, Mario & Sonic at the London 2012 Olympic Games has sold over two million copies since its November release.

The mediocre outing reached 2.39m sales in the last quarter, easily dwarfing sales of the far superior Sonic Generations on PS3, 360, PC and stablemate Sonic Generations on 3DS: across all four versions, Generations managed a combined 1.63m sales around the world.

The sports title gave SEGA a considerable bump in unit sales on Wii, selling 2.8m Wii games in the past quarter compared to 1.42m in the same period last year.

Mario & Sonic at the London 2012 Olympic Games on 3DS is out next week. With SEGA's 3DS sales in the past quarter standing at just 620,000, can it become the publisher's biggest 3DS game?
