hmmm... good question. I feel like vamp is too busy at cheer practice and hanging out that she doesn't play many games. I reckon she has a portable console like the DS and has 100%'d everything she plays on it due to omniscience
vamp has a taste for outrageously pink & girly stuff so she'd probably play all the games where you can be princess peach (most of which were never released in this dimension)
