Hi mate, SOF2 copies are rare at the moment. Production was stopped quite a while ago and it's no longer supported. I know of a shop in Brisbane where the owner recently had about a dozen copies saved only for people keen on playing Multi-player. He doesn't even have them on the shelves - LOL.
If you want to try before you buy then get yourself a pirated copy and a key-gen and play on Optusnet. They have disabled key checking in the Punkbuster server settings. This is because the game is no longer supported and because of diminishing players (so I was told).
Learning SOF2 is much easier than learning ET!!
There are many major differences though... I"ll chat to ya next time on TS about it all. Have a look at the trailer -
