Playstation`s online is free too, but you needed to pay for the online pass to play BF3 online and that era`s Tiger Woods game. It only changed in BF4, and it was £8.00. Think they stopped it coz of next gen and ps4 needing to pay for online, like xbox. Kinda backfired though as the vast majority still play last gen, inc me, and itll be a few years before the bigger percentage are next gen. Ghosts looks just as good on ps3 as ps4, and Titanfall is the same game on 360 as x1. Watchdogs looks the same too on every console.
Unless you have a great eye for detail, and very few have, and you have a top of the range tv, then you wont notice any difference.
