You guys do realize that PSP's tie ration isn't actually that bad right?
It's a 3.7 on Vgchartz. Which looks bad compared to consoles... however, look at other handhelds.
Gameboy is a 4.22 and just happened to be synonymous with handhelds.
GBA 4.6
DS is a 5.0
3.7 isn't bad considering handheld tie ratios and that the PSP just wasn't that popular.
If the tie ratio was hurt, it wasn't due to piracy causing a loss in software sales.
It was due to piracy creating an INCREASE in hardware sales.
I knew people with pirated PSPs. They bought them so they had portable SNES/Genesis emulators.
