It's a rough subject. When it comes to illegal downloads, i've always had a stance on whether its actually physically attainable by any other source. I completely agree that the whole "I own the original game" thing is pure bullshit. If you own it, go play it. Every now and again i have a look on ebay to see what games i can aqquire for my megadrive (genesis) or SNES (Famicom). Sad fact is, some games cannot be got hold of. Those that own them don't want to sell them, and those that don't want to own them. It's not the consumers fault that the products don't exist anymore.
Near as damn all the decent PS2 and X-Box games are easily still aqquired, and by all rights my ps2 collection is big enough, so that area alone, but theres so many games i didn't have for my childhood consoles because my parents money bought games, so they were few and far between. I missed out on the entire battletoads series and as such downloaded them, enjoyed them, and then deleted them. That meant i could talk to a friend who once owned them, and had a, well for him it was a reminicing discussion, for me it was a talk about 5 minutes ago.
I think its a shame that companies are holding licences to games they no-longer produce. How the fuck do they expect us to play them now. I know that would cause people to wait till a games copywright expires and then aqquire it for free. But those same people would probably download it illegaly anyway.
I say yay for roms that are for games no longer produced, but don't go mockin the companies for being pissed when people are downloading games that are still on the shelves
