It's not a Mario-level sales explosion or anything, but certainly not bad for a 3DS debut, and not bad for eight days of sales. By the way, Kid Icarus: Uprising is wonderful.
Meanwhile, February release Resident Evil: Revelations sold around 122,000 in March, the NPD told us. All we know about its February performance is that it was somewhere in the top 25 games.
Update: We're asking the NPD for clarification regarding the Revelations sales numbers, as questions have arisen as to the possibility that it could be life-to-date rather than March. We'll update accordingly when we hear back.
