I have both and buyed the bundle anyway... as gift. Now I need to guess how to split the bundle to gift the DRM-Free Grim Fandango to somebody...
The only solution I can think of is to gift the whole bundle to someone and then he can give the steam keys to someone else.
Dunno if splitting the bundle is not agains HB policy, I remember there were some intense disscussion about it in the past.
BTW: Upgrading still working like in the past? (if you buy a $1 tier then, while upgrading to BTA, you have to pay only as much as was the BTA when you bought $1 tier)
