Sprinting between E3 appointments, I found time to swing by Sony's booth and spend a little hands-on time with a copy of Gran Turismo loaded onto a PSP go. Just a few rows down, LittleBigPlanet was being shown on PSP go machines, too.
Gran Turismo, as one might expect, looked like Gran Turismo running on PSP. Without knowing too much about Gran Turismo (I'm more of a Ridge Racer guy), that's about the best observation I can provide for TheFeed readers: this looked like an excellent version of Gran Turismo running on PSP.
Oddly enough, my time with PSP go provoked similar feelings. PSP go didn't feel much different than the older PSP that was sitting in my bag. The analog nub is notably smaller and seemed less twitchy -- if that makes any sense. The differences were a little intangible. At first, PSP go felt much more natural, but after pulling my old launch PSP out of my bag, it didn't feel too much different. In general, it's more of the same -- depending on how you feel about PSP, that's either a good or bad thing.
Unfortunately, at least in the public E3 kiosks, Sony has PSP go hardware tied down. There was no way to drop the PSP go into my hands and see how it felt to play a game the way I would in real-world circumstances. Plus, there was no way to slide the screen down and see how small the PSP go feels.
If I'm able to get my hands on a less restricted PSP go, I'll report back.
