THERE IS NO JUSTIFYING IT.. BUT IF YOU WILL HAVE FUN PLAYING WITH IT FOR YEARS TO COME SO ITS NOT WASTED MONEY
You don't need any justification to use your own money. (it will be another completely different matter if you sold your kidney....)
Buy a used PS3 and used games and it should be pretty cheap. On the other hand, chances are Drakengard 3 and Nier will end up on PC eventually, you could just wait for that. On the third hand, there's The Last of Us, Ni no Kuni, Tales of Xillia, and the HD remasters of Ico and Shadow of the Colossus. I'll also add that I definitely do not endorse buying a modded PS3 that can play ROMs that you've downloaded for free, eliminating the need to actually buy any games, because that's illegal and also much cheaper in the long run.
This isnt a situation where u can ask for more pros to buying a ps3, it's more of a once u buy it, you'll figure out what type of games are available once u buy it. It's a gamble in short.
Ha ha, no i mean like u don't know exactly what games are good (or what games you'll like) unless u play them. I've watched games.and liked them, but i got bored. Some games with great reviews but ended up being a waste, etc.
Are those games exclusive on that platform only? Are those games would not be or less probability to be ported to ps4 or pc? Are those games are really good and you reaaaly want to play it? Are those games not available in psnow? Do you have no friend nor relative that you could borrow for that console? Then do it. If its worth it. DO IT. DO IT FOR THE GAME, JUST DO IT ✓
PS3? Just remember that the HDMI port is quite easy to damage... Just one lightning bolt and you'll be spending time playing on VGA port for all eternity...
PS4 can't play PS3 games? Aren't they backward compatible? Anyhow, unless you have a wife, there's no need for justification. If you're not saving money for something more important (like a flood or wedding) then use it. Who knows, you can die anytime. So no sense in keeping your money in the bank where it does nothing good. Also, if you are suffering any illnesses with imminent threat of death, you can put Ai-chan on your inheritance list.
It's surely worth it if you want to play the games, go ahead and buy it. I bought a PS4 just to play Touhou Genso Rondo, that's 5x my income for the console + 1/2 of my income for the game... I don't regret it one bit, would totally recommend it to anyone. Wanna buy a PS3 because of 2 games? You're already better than me, and it will be cheaper too! Buy it! \(^^)/
PCs don't run exclusives... >.> I doubt anyone would buy a PS3 if it wasn't for the exclusives... And judging from the OP, that's what he wants.
