you want to say that nowadays we have the same number of retail releases we had in the previous generations ?
I don't want to say anything, you are the one who stated that 21 games were probably the whole vita Q4 trying to make your point stronger. That web shows 455 retail packages for vita in its ~3years vs 2543 for PSP in 10years. Taking into consideration how the former is underperforming versus the later, I don't think the ammount of software is its biggest problem, but the lack of enough diversity and appeal to atract bigger demographics with those titles.
I thought these threads were based on discussing facts and not our probably not so accurate feelings.
