As we understand it - its legal to make a copy of your own game. And it makes sense to get copies made as we can keep our original disc in mint condition. And hey, when we lend to a friend, we don’t have to risk our favorite PSP game getting damaged! 
But, with times being so tough - and PSP sales sliding downwards so hard - this whole copying gig may just be another way that Sony a losing sales.
At least, that’s what we figure might explain the latest experiment Sony are trialing with Patapon 2. Because this game is not being made available with a disc! It can only be got by downloading from the Playstation store (you can buy it from a store - but you just get a download coupon to take home and then use to download from the online store)
So no disc that can be copied! And no hard copy to sell, either, when we are done!
So while this might be good for Sony and game developers - it does not look too good for us! After all, the game is not any cheaper (its the same price as Patapon) - but we can’t get any $$ back by reselling.
Is it worth it - well here is a trailer of the Patapon 2 game for you to check out:
Not sure how smart this is as it also means we have less $$ to buy new games. Hmmm - well, we’ll see how this experiment goes.
