I am a mostly Nintendo gamer, and I also buy on PC. But I don't buy the multiplats on my PC, justa small few. I mostly buy PC oriented strategy, indie, puzzle, or RPG titles and not things I could necessarily find elsewhere.
I don't want to play Assassin's Creed and I don't really want to play Killzone or Street Fighter or Need for Speed or CoD. I would not buy them if my main was a PS3. There are other games to play.
Also, I suppose I've gotten used to Nintendo titles keeping their price and simply buying them new at almost full price. With third party games... I simply feel far more hesitant to shell out 60, 50, or even 40 dollars. I feel I can just wait for any third party game I had an interest in buying to go below $30. Then when it does sometimes I buy it but many times I've also lost interest by that point.
