Okay! So I've just done a system restore on my PS3 so that I can sign up for a new account on PSN that enables me to pay for my own content from the PSN store. There's a few new games I want to play, but should I play through some of my older games before doing so? I'm not too worried about loosing trophies, but should I play though my older games anyway? What do you think? The games that I want to get are Killzone 2, Street Fighter 4 and Resident Evil 5.
