If a recap is sufficient, then you might as well just read a recap of the entire trilogy!

The first is my favourite. Except the inventory management.

i would defo not skip 1 unless it was impossible for you to play it. there is a ps3 version but i think you need to buy all three as a trilogy collection on ps3. don't think you can buy it individually

you can on xb360 but then you can't transfer the save file. that's not a big problem though.
