And just about 5 of those titles are still relevant.

Playstation did get lucky, but only in the sense that both SEGA and Nintendo screwed up with their consoles. These screw ups left an opening for a newcomer that did things right, and Sony's smart decisions with the Playstation exploited that.

Anyway, if Playstation weren't around, than either SEGA, Nintendo or Microsoft would gave filled the void. If you mean the original Playstation, developers would have simply needed to work with N64's cartridge limitations and learn to work with Saturn's difficult hardware. Both the Saturn and N64 were successful in different regions; N64 in America and Saturn in Japan, so the industry certainly could have gotten buy without PS1.

If you mean PS4, either Xbox One or Wii U are more than capable of filling in for PS4. Xbox One may have needed a price cut first, but afterwards I'm sure anyone who wanted a next gen console would go for it.

An entire industry viable industry wouldn't fold over the absense of one competitor, especially when there are so many others trying to compete. This is kind of like how peopel say Nintendo rescued the American gaming industry, when there are many other companies that would inevitably have tried to fill in the gap left by Atari, like SEGA or NEC. Certainly, Nintendo was the first company to have the balls to do it and the intelligence to do it right, but America was too big a market for these other companies to ignore forever. 

Its very hard to even try to predict somethign like this, things wouldve played out very differently. But maybe someone woul step in and fill Sonys role in this story or Nintendo would just realise the potential of the mature gamming market and invest in it and be super dominant selling the usual fun games they do + the mature ones. Or maybe wed all be playing in PCs.

Its realy very hard to say what would have happened.

again, we had mature games before the PS, that was nothing new. new was that it was cool for teens to play video games, casuals dont like uncool things, so they didnt like gaming before.

I guess my issue with this is the assumption that there'd be entire demographics of unhappy people without a console to play if Sony wasn't present... If anyone abhors a vacuum more than nature its your average corporation, and someone would certainly have filled whatever void Sony left as time went on.

I do agree that it's sad to look at that list of games (many of which would have existed without Sony mind you) we'd never have received, but it's possible we'd have an entirely different list with someone else. Sony's "innovations" extend mostly to marketing to non-gamers via focusing on the DVD player and being very hands off with 3rd party developers (granted Sega did this, but Sega was too busy releasing their 32x for a half year run to recall that they likely ought to advertise their Saturn).

Mind you I've always loved my Playstations and fear I'm coming across too harshly, but I don't see any out-there innovations from them that someone else wouldn't have eventually done. Really, they succeeded by just not doing anything stupid... If nintendo had gone optical drive with the N64 Sony's run may have been a short one, but they entered at a time when both Nintendo and Sega had their respective heads up their asses.

Sony popularized Tomb raider and from I've read about it, it was released on Saturn, Playstation and PC originally.

FF7 probably wouldn't of been created or been the game as it is without playstation.

You're right about grandia and Tekken. On the tekken series, i'm mainly seeing only arcade and playstaton consoles as their platform. http://en.wikipedia.org/wiki/Tekken

Why did you mention dreamcast with dino crisis? It was released on playstation first and then it was ported to Dreamcast later.

Tob raider Populized the PS, not the PS tomb raider, and it was planed as a Saturn exclusive till they saw how ba the saturn is doing in the west.

and they were developing FF7 for the n64. they just switched to the PS because they could have a lot more cutscenes on he disc and better music Quality. the gameplay itself wasnt limited by the n64, and could have looked better on n64(because more power).

and dino crisis got a late port yes, but well it was sega, we dont realy know why the port was so late, maybe they switched from satur to DC. making just 1 next gen port is strange.

Someone else would have stepped into the market after a while. History wouldn't have altered that much unless that company would have stupid policies or hardware.

Without PlayStation I think the industry would have been just fine. Nintendo would be bigger, and Sega would still be alive and well. The Dreamcast would have gotten the praise it deserved and most likely Sega would be a powerhouse in gaming. 3rd party devs wouldn't be making rushed half games with massive day 1 patches because they wouldn't be given free reign and they would be held accountable and held to standards. Companies like Naughty Dog would be 3rd party and their games would be available for all.

While I would be glad that Nintendo got bigger, the biggest change would be that Sega is still a console maker.

honestly i believe so, yes. if it werent for PS4 then MS probably wouldnt have changed their DRM policies and the XB1 would have flopped BIG time. and the WiiU was already dead by then. i can imagine PC doing better but not enough to sustain the entire industry by its self.
