Mainly Japanese / Foreign video games, they're great for boosting your gamerscore. :rolleyes: Apparently the guy who has the most gamerscore on Xbox LIVE acquires his through games which aren't usually sold in stores.

I believe there is a Naruto game which gives like 10k Gamerscore in 5 Achievements. And I'm pretty sure they're all about a combo attack. Such as: "String together a 20 hit Combo" = 1k , "String together a 30 hit Combo" = 2k, etc

There's a really old Avatar the Last Airbender game that takes about 10 mins to get 1000g, also TMNT is another where it's easy as shit. Walking Dead games are fun and easy as well. Also, Fight Night Round 3 is good.
