The number of trophies included in PlayStation Network games will remain unchanged despite Microsoft's decision to increase the achievement count in Xbox Live Arcade titles, Sony has confirmed.
As of next month, all Xbox Live Arcade titles will have the option to increase from 200 to 400 Gamerscore points, with the addition of up to 30 achievements. The new 400 point ceiling will be mandatory in all new XBLA games releasing from June this year.
Many games released on both XBLA and PSN have the same unlocks for achievements and trophies - but Sony told IGN it won't change the way it does things.
"There are plenty of downloadable games on PSN that currently offer platinum trophies," an SCEA spokesman said. These include Dead Nation, Rocketbirds and Trine.
The spokesman added that Sony has "a standard and consistent system to determine the trophies available for a particular game. The overall scope of the game determines the trophies available, not method of distribution".
