I used to think a unified platform was a great idea, but I' ve totally changed my viewpoint on it. There are too many glaring flaws to make it a good thing, or even functional.
Having a unified platform, in the sense that there would be a unifying standard for game performance, and a unified software performance specification would certainly be a bad thing. Some of the best looking games of our generation have come from developers exploiting specific hardware strengths in their respective consoles. With few exceptions, multiplatform games rarely look and play identically on their different consoles, and the ones that do aren' t amazing looking.
Having a unified platform, in the sense that there is one standard game console that all games play on is an even worse idea. The lack of strong competition would bring about an iPod syndrome in the games industry. They almost certainly wouldn' t have a
total monopoly on the industry, but would have enough to charge exorbitant amounts of money for their average products, with people coughing up the cash left & right. Not a good thing.
On top of that, if there' s no competition, why do they need to fight to make a superior product?
Do you want WiFi? Too bad, we don' t feel like putting it in.
Do you want format support for media playback? Meh, we' ll get around to it... eventually.
Want better graphics? Wait for UniBox 4.
It sounds good in theory, but then again, so does Russian Socialism.
