This is good, I think
It looks like the limit on Achievement points for Xbox Live Arcade games on the Xbox One will be rising to 1,000, instead of being only 400. On Twitter, PopCap Games tweeted that Peggle 2 will have a Gamerscore of 1,000, and the post for Halo: Spartan Assault on Xbox 360 Achievements, lists the game with 30 Achievements that are worth a total of 1,000 points.
I’m not really a fan of Achievements, and the fact that they have scores disturbs me, but I can see how this is a good thing for the folks that care about their Gamerscore. A lot of XBLA games are becoming more involved and bigger than games on the Xbox 360, so it makes sense to give them the same guidelines as full retail games.
