I've been playing Hot Shots Golf Open Tee on my Sony PSP and I have to say it's pretty fun. The graphics are top notch and there are a load of collectable items and customizable outfits that you can win for your character.
I think the game would be even better if the multi player mode didn't happen only in wi-fi. That's my only gripe.
The multi-player golf is a mode that lets you play with up to 8 people on the psp's wirless LAN function in Ad Hoc Mode.
There should be a two player mode where I can play with someone else and we take turns on my one psp.
