Asked if he was disappointed with the game's performance, Sony Computer Entertainment UK MD Fergal Gara told MCV: "It could have sold better, but it sold respectively well."
Next up for PS3's augmented reality peripheral is detective caper Wonderbook: Diggs Nightcrawler, which was recently given a May release date.
Gara said: "I am encouraged that we have more titles coming and it may just take a little longer to get it to settle in consumer's consciousness.
"It was also relatively expensive if you didn't already have a PS3 or a Move controller. But I think as people learn it's about more titles, then that would give it some added momentum."
SCE UK marketing director Murray Pannell also said: "From a marketing perspective, Wonderbook was an important step in becoming more family-focused as a platform. That is not an easy job and can take years to achieve."
