I can chime in here... as I've pirated tons and TONS of iOS apps.
Once you know you can pirate them, the sense of value attached to individual apps is lost (Still, to this day, I do not consider apps to have 'value'... same with movies and CDs...I can't fathom spending money on them)
Then you want to try them all, etc..... I guess the question becomes, why NOT pirate the game, $2 or $4? Money saved is money saved.. and downloading pirated iOS apps is as easy as the regular store once you have everything set up. If there's 20 iOS apps you want to load on your iPod touch, you are probably a bit loathe to drop $40-$80 at once... but it's no problem to que them up in hackul0us (sorry if this is old, been a long time since i've had an iOs device)
