With Rift going F2P, you should combine Bits with the real money in that game

[Cutlass Jack]

Like Perfect World does with "Zen", and Sony does with "Station Cash" (ie. they use the same real money currency across all their games), you should turn Bits into like a "Trion bucks" thing so it can be used in both Defiance and Rift.

Just sayin! If this were true, it would definitely encourage me to buy some of it.

I'm guessing you aren't too familiar with how Perfect World's Zen actually works.

You can't actually use it cross game. You have to permanently transfer it to the game/server you want to use it on.
