Report: XBLA achievements limit set to increase to 400
X360A is reporting that Microsoft is to expand the limit of achievements in Xbox Live Arcade titles from 200 points to 400.
Existing rules see current XBLA titles gaining 200 achievement points with a limit of 20 achievements per game from the outset. DLC currently adds 50 achievement points per quarter for a total of 350 achievement points.
The new rules now mean XBLA titles from June 1 will have to include mandatory rules, featuring 400 GS from the base game and 100 GS per quarter with DLC on up to eight achievements for a total of 800 GS.
Games that release between April 1 and May 31 on XBLA will have a choice to choose between the new and old systems, including Grasshopper's Diabolical Pitch on April 4.
