Given how the US market (esp. at this time of year) is dominated with sports titles and FPS, I guess it's not too surprising Mania was gone from the US charts that fast, despite opening at #3. Still disappointing though.
That said, while it debuted at a lower spot (#8), I really expected Mania to have a better treatment from Europe though; given Sega/Sonic's popularity there. Crash took a hit but was still able to hold on, and somehow Rayman Legends was able to actually get back on the charts, despite having been available for years now. At least it's still making waves on the eShop at least.
Wow at MvC: Infinite Bomba and Knack 2 cracked. Cacpcom and Sony am cry.
