Let's say you're a Nintendo fanboy and wants to sabotage PS3 and Xbox360.

You should spend as much as you can and buy all the opposing consoles.

This way, you'll stiffle the software sales since you don't be buying any of their games.

When the publishers see that they can't sell software, they'll flock to your console of choice.

You'll also have to convince your fellow fanboys to do the same. Strenght in numbers, remember.

This technique is super effective when the opposing console is being sold at a loss. ie: PS3 released at $250 loss. So, the more console you buy, the more they loses they get.

Now, go, fanboys, and buy up all the opposing consoles.

Here you are:

Thank you, my friend. You are doing your company of choice a great favor.

I don't have too for every two players buying x360 in Poland one of them will never buy any games :)
