Sonic CD's topped the PlayStation Network sales charts for December.

The acclaimed Mega-CD release (or SEGA CD depending on your location) fought off strong competition from NBA Jam: On Fire Edition, Payday: The Heist and Trine 2, all of which rounded out the top five.

Despite releasing right at the end of the month, Oddworld: Stranger's Wrath HD managed to shoot its way into the top-twenty, finishing up in thirteenth. Meanwhile the digital release of Call Of Duty 4: Modern Warfare showed its legs by climbing into an impressive eighteenth.

On PSone, Final Fantasy VI temporarily toppled Final Fantasy VII, while Corpse Party held onto its position atop the PSP download charts.
