Game price can't alwasy be looked at as the starting price tho. I almost never buy a game at full price. I wait for sales or buy used nearly all the time.
PC games drop in price the fastest. I bought Tomb Raider not 2 months after release for 29.99.
"And like i have mentioned before that advantage is offset by all the free games you get with PS Plus and Live Gold."
Which you don't own and can't play if you don't keep paying for your subscription. So, they're not free at all.
