Actually, yes. For awhile, I was completely closed to the idea of buying new games outside of franchises I knew I liked. In the course of my four year active duty enlistment, the only game I bought was Supreme Commander... because I used to love Total Annihilation, and I used to complain about a lack of a strategic view in said game.
...since beginning to watch ZP, I've bought Psychonauts, (most of) the God of War series, Portal, and Batman: Arkham Asylum (and a few other games here and there that Yahtzee didn't influence). In short: I spent about six years not being a gamer, and I'm slowly working video games back into my life, because really... they're cheaper than most of my other pastimes.
