The GPS games: more details revealed
Of course, Hot Shots Golf isn't the only game using PSP's GPS feature. Read on to see how other software is taking advantage of the device.
The PSP's widescreen is noted as a significant advantage for GPS users: you can simply see more of the map at once. The automatic route guidance (featured in many modern cars) will tell you how to get to a location, and can be used both in the car, and when walking on foot.
Homestar allows you to use the GPS system to see the stars up in the night sky. I don't really understand this screen from the software, but I'm sure fans of constellations and star-gazing will be able to decipher some sort of meaningful data out of this. Once again, it appears the PSP is being used to attract non-gamers to get the system.
Metal Gear Solid: Portable Ops allows you to randomly generate new characters based on the wi-fi points you access during multiplayer play. However, it appears that there may be more functionality added for GPS users. It appears that you'll be sent on a treasure hunt, which tracks your location via GPS. (Of course, someone proficient in Japanese can try to translate and find more info!) I'm glad that MGS is using the GPS feature, but so far, it appears very, very gimmicky (but Kojima does love using gimmicks).
