All depend on how long the gonna rent their games for the amount of $5 or $6, it will definitely good for some people maybe for other not, let's see..the time will say
this is why i will never sell my old consoles or games, so i don't have to worry about wanting to reply ps1/ps2/ps3 games, since i have them all and can still play them;), also i disagree with what they said about getting a new console means you don't what to play old games on there, i would definitely play ps1/ps2/ps3 games on my ps4 if i didn't have my ps1/ps2/ps3 consoles still :)
5$ for 7 days non-streaming new game = Awesome but it should be cheaper for older games.
5$ for 7 days streaming new/old game = BAD, why? not just because of the lag you will experience when playing a game on a shitty server but also... when you have no internet.
5$ for 7 days streaming new/old ONLINE game = Epic fail, i mean BAD lol. Why? because it will lag so bad that you just couldn't play it.
What i have shown you is reality. What you remember... that is the illusion.
