MY PS3 and PS4 are both busted. PS4 broke 1st of January, just 12 days after warranty and only played it maybe 4-5h in that time frame so most likely had defective model begin with. My PS3 which is first gen with backwards compatibility and 4USB outlets got yellow light of death though that is acceptable as I have had it for over 7 years. Just took it to repairs yesterday and should be repaired in next few days. Anyways, as of now I have been playing my PS Vita so I might give AC Liberation a try. Still gotta beat AC4 before I will get unity though and as my PS4 is busted and I'm not in a hurry to repair it, so it might be a while before AC: Unity will happen.
