only ps3 slim or some fat models can be modded..
new super slims aren't modifiable
best bet is to buy used games and later keep on trading those for other games
(takes time but savings will be huge this way )
buy 1 disc for 1000 play it for 1 month finish the game
sell it for 8-900 , then buy other games play it and again sell it
keep hold of 3-4 great online multiplier games ( 1 fifa , 2 shooters , 1 nfs ) ,
even better is the play station plus subscription 3000 rs for 1 year which allows downloading many games for free and we can play as long as we have the subscription
that's what i have read
but still it doesn't come even close to the tempting piracy thing
ps3 gaming is a luxury experience
