There's some boost on at the minute, I logged in for only the second time ever (after playing 10 minutes yesterday) and immediately get 1,000,000G and the Going For Gold trophy. But I still only have 600 GP. Any advice for getting more?
Ed; also! What's the G actually used for? Seems like GP is what you need to unlock stuff, is G actually good for anything? --- Oh no, there goes Toh-kee-yoh! http://www.rockband.com/users/Dark_Raven_X
Normally, you will get 100 gift points after every ranked battle. For this week, as part of a promotion, you will get 5x the amount of gift points if you play ranked using a PREMIUM TICKET or a PREMIUM COIN. This is fastest way to gain gift points at the moment.
As of right now, G is only used to upgrade your character stats. However, it might be used later on to buy customization items or characters, but that's just speculation though.
