One might regret having to buy ps + to play online unlike the ps3 especially as the quality of online is not as good as this (although I find a slight improvement nonetheless).
We can console themselves with the small advantages that can be more like 3 free games, etc ... but it still remains quite regrettable to still reach for their wallet.
After all, 4.20 / month for online play is not much but it would still have that quality is at the rendezvous ...
