It has been more than three years since the last Splinter Cell - Splinter Cell: Double Agent - and the new sequel isn't out yet. The game's production manager Andréane Meunier revealed that this wasn't the original plan and that the game was getting ready for release in 2007 when they found out that it wasn't on bar with the series' quality.
"Actually we felt that the game wasn't well received [at Ubidays] and some of the critics were actually saying that we were missing the gameplay, when we started having maybe a bit of trouble bringing back the core gameplay, and we saw the success that Assassin's Creed was going to have, Ubisoft made the decision to say, 'Look guys, take the time you need to do this game, we've got someone bringing in the money for the next year so we're okay, we won't ship a game that's not good, so go ahead and take the time to do it," he said.
"That took the pressure off us and allowed us to rework the core values that we wanted to bring out."
Splinter Cell: Conviction has been delayed several time since then. The game is now slated for release early in 2010.
