It was a good month for US video game sales (overall up 9% compared to February 2013) largely thanks to good hardware sales from PS4 and Xbox One (software sales were actually down for the month).
Top 10 Software (combined sales):
1. Call of Duty: Ghosts (Xbox 360, PS3, Xbox One, PS4, Wii U, PC)
2. The Lego Movie Videogame (Xbox 360, PS3, 3DS, Wii U, Xbox One, PS4, Vita)
3. NBA 2K14 (Xbox 360, PS4, PS3, Xbox One, PC)
4. Thief (PS4, Xbox One, 360, PS3)
5. Grand Theft Auto V (Xbox 360, PS3)
6. Battlefield 4 (PS4, Xbox One, 360, PS3, PC)
7. Assassin's Creed IV: Black Flag (Xbox 360, PS4, PS3, Xbox One, Wii U, PC)
8. Lightning Returns: Final Fantasy XIII (PS3, Xbox 360)
9. Minecraft (Xbox 360)
10. Bravely Default (3DS)
Nintendo issued some statements, Bravely Default sold a combined 200,000 copies (digital + physical), while Donkey Kong Country: Tropical Freeze sold 180,000 copies. According to Nintendo these ranked as number two and four respectively had the list only taken individual SKU's into account (Minecraft on Xbox 360 would then be number one). Another thing of interest is that overall software sales (we presume this is physical only as this is what NPD Group tracks) is up 80% on PS4 and Xbox One in the first four months compared to PS3 and Xbox 360.
While official numbers for hardware to come by here's what NeoGAF have been able to piece together:
"PS4: 258,000 / 0.9 = 286.7K (Though XB1 is "over 90%" of the PS4's sales, so it might be a bit lower)
Xbox One: 258K
Xbox 360: 114K (-62.2%)
Wii U: Nearly 82.5K (+~25%)"
Even if Wii U is still at a low number it does show some growth year-on-year, which is a positive.
