Some say piracy is wrong but it feels so right, I encourage all to give it a go. You may come to like it.
Anyway I mainly buy 360 games. They are about £2 each when I buy them as it seems nobody wants 360 games any more and let most of them go cheap. All you retro kiddies that look back to the 90s when the same thing happened for the 16 bit era stuff do take note.
Writeable dual layer DVDs of quality worth speaking off are about £1 a pop these days, and while burners are slightly more reliable the failure rate is not insignificant, especially as I am sure manufacturers include motes of dust in them larger than anything else I see in day to day life. I also rarely have more than about 2 gigs of easily accessible space which conflicts a bit with the average 9 gigs + space needed for repair + all doubled for extraction you see there.
Some might also say it allows me to take discs round my friend's house but frankly I would not be friends with anybody that only had a stock 360.
On supporting devs then there are almost always more willing to take a chance and make something... I say having not had a rampart clone in years and space sims being thin on the ground. Oh well, at least we get to revisit world war 2.
