The Chrono Cross team has been making Final Fantasy XI add-ons and that MMO-RPG for the 360/PS3 for ages.
The Xenogears team did go and the Vagrant Story/ Final Fantasy Tactics team needed 5 years to complete Final Fantasy XII, almost a whole generation for one game.
Most of the talent is still there, but there games take to long in devolopement and they are wasting there talents on to much Spin-offs and Final Fantast XI add-ons.
