I don't buy video games often because they cost so much money. It's at least $30 a piece for games for my 3DS and $50-$60 a piece for games for my Wii U. Since games are that much, I don't buy a video game that often and I make sure it's a game that I really want.
Purchased pretty much none in 2014 due to not wanting to play them on my X360. Now I have a PS4, I'm back to buying a lot of games. I'll cool down until I complete them now though.
