For the third generation in a row, I would say Sony has emerged as the front-runner in terms of overall software quality and variety. But all three generations got off to somewhat rocky starts; perhaps the worst was the most recent.
I've said it before: the only reason I got the PlayStation 3 on launch day was because I needed it for work purposes. Left to my own devices, I really had no intention of shelling out $600 for a system that didn't have many games I desperately wanted. Blu-Ray hadn't won the HD format war yet, the PlayStation Network was in its infancy stages, and there were some reliability questions. I remembered working at EB during the PS2 launch, and there were definite issues when new owners tried to stand their new systems vertical. Also, let's not forget that PS3 availability was atrocious at launch. I mean, 6 per store in many places?
As it currently stands, I've got about 75 PS3 games, Blu-Ray is the only HD format, the Network remains free and in my eyes, offers just about everything you get with Live, and I've had two PS3s, neither of which hiccuped even once. And if I were to list the top 10 games of the generation, I'd say at least five or six would be PlayStation 3 exclusives. But you know, Sony may not learn from history…they're trying to say they have learned by delaying the launch of the PlayStation Vita for the sake of a lot of launch software.
The question remains, however- do you think Sony will repeat the same mistakes when the PS4 launches? As in, too pricey, not enough games, quite simply not enough features to warrant the price, and an almost complete lack of availability? It'd be hard to believe they'd do it all over again with the PS4, but who knows?
