Gifts with asterisks?

Wait so since I gave away 1 bundle game (Say it was 30$), if I go give away a 40$ non bundle game I'll only get 20% of that non bundle games value? or do you mean:

A Bundle game "worth" 50$ will only come up at 30$ + 20%?

That's not exactly right. The contributor value is counted this way:

The first $25 of your bundle contributor value counts as normal (non-bundle) contributor value. Then you get 20% contributor value from non-bundle games extra, which makes $30 (because the first $25 count normal). For every other bundle bundle game you get only get 20% value of your non-bundle contributions. When you give more non-bundle games away you get these 20% of their value.

I hope I explained it good ;), else take a look at this.

I'm not talking about non-bundle games

No matter how many bundle games you give out your contribution value will not rise above $30 unless you give out non-bundle games then it will rise from the price of the game
