A good starting PSP library

Okay, I don't even own the system yet, but I preordered the Big Boss Bundle yesterday. In this inbetween time, I plan on occasionally picking up games here and there. The problem is that the system has been out for quite a while and I'm not exactly sure where to start. (Is the system region free) I guess I'm looking to fill a few genres:

Fighting - What is the all around best fighter on the platform? I'm more of a Street Fighter person, but I like Tekken as well. I don't necessarily mean the best playing one either, but the overall package. Which one has the best multiplayer/which one uses wifi/ does it perform well?/is there a community around the game. I'm definitly pick up Power STone Collection, but other than that I don't know. Any "old" school Street Fighter games on the system?

RAcing - Is Gran Turismo really the best racer on the platform?

Golf - Pangya, Hot Shots, or Tiger Woods? Leaning towards one of the first two as I usually find Tiger rather bland. Also, how come the first Hot Shots is rated higher than the second?

Action - God of War? Anything else worth it off the bat?

FPS - one analog stick scares me. Suggestions? I was thinking about Star Wars Battlefront...

Collection Games - any suggestions?

You should get these games :

Final Fantasy VII : Crisis Core

Tekken Dark Resurrection

Tales of Eternia

Resistance Retribution

Metal Gear Solid Portable Ops

God Of War - Chains Of Olympus

Killzone Liberation

Secret Agent Clank

Daxter

Ratchet and Clank Size Matters

Syphon Filter Dark Mirror

Syphon Filter 2 Logan's Shadow

Little Big Planet

Jak and Daxter : The Lost Frontier

Assassin's Creed : Bloodlines

Dante's Inferno

MGS Portable Ops is pretty good if you're into Metal Gear.

Edit: nvm, beat me to it ^^

First of all, the PSP is region free. Here are answers to your questions:

Fighting: Tekken 6 is propably the best.

Racing: Kind of. The Midnight Club series is also great.

Golf: Hot Shots Golf is great! Havent tried the other ones yet.

Action: Definetly God of War. Dantes Inferno is also pretty sweet.

FPS: Its no problem with one analog stick when you get used to it. Try the FTB series and Resistance.
