IMO, why would one want to hack/mod their PS3 to download/burn PS3 games to play them? Unless maybe you have unlimited bandwidth but still its somewhat pointless. My internet provider is Rogers with a 60gb bandwidth cap.
If i download, lets say, MGS4...50gb, that leaves me with like 10gb for the rest of the month? No thanks i need other stuff to download to last me a month.
And then i have a $2.00 fee per 1gb over my bandwidth, so say i've already exceeded my bandwidth from downloading other stuff and i later decide to download MGS4...50gb x $2.00 per 1gb = $100 on top of my normal internet fee whereas i could just buy the original game for $29.99 without having to put the effort to hack my PS3 properly and its seriously legit incase Sony tries to ban your account if they find out your PS3 is hacked.
Dont forget if you want to burn them on disc, a BR burner & BR disc arent that cheap. And to make good use of the money spent on the disc and burners you dam well better download alot, but thatll kill your money more cause you'll probably exceed your bandwidth.
As well, downloading such huge files might take awhile, I dont want to pause my downloads everytime i play online or else im just going to lag throughout the downloading process.
In the end i'd tell myself im an idiot for going throught all that time & money when the easier, safer and better way is just being a real owner and buy the actual games.
On a side note, I modded my PS2 and the of the games i burnt, i ended up buying the actual game cause its worth to buy them and collect so my mod became irrelevant lol. Learned my lesson that its pointless for me to mod a console.
