Arkose: This would be interesting if
GameTap didn't already exist doing the same sort of thing but with a selection at least 50 times bigger. That's on top of the obvious advantages of GameTap running games natively, supporting modding, offering classic console and arcade games, being available in several countries (as either GameTap or
Metaboli), and working on any internet connection; I've used GameTap in New Zealand, which isn't even on a supported continent (let alone near a data centre), and the experience was flawless.
cogadh: Just playing devil's advocate here but, the OnLive client is free, so no cost like buying a $200+ console and even if you go with OnLive's "console", it's only $100. Right off the bat, you've just saved a ton of money that makes a console not worth the cost in comparison.
Arkose: Note that the subscription is only available to owners of the $100 "microconsole". Additionally, most of their library isn't available through the subscription which means you're stuck with either having a lousy selection or paying for some games separately for the highest rental period. The "Full PlayPass" costs as much as a retail copy but expires after three years, and of course you can't buy used or trade in games like with any real console.
Regardless of how you get into OnLive it's only cheaper for the initial outlay; over the life of the system it's much more expensive, and the three-year cut-off combined with the intangibility of everything means you're left with nothing at the end of it. Many gamers still fondly treasure their NES or Genesis and pull it out occasionally to relive the good times, and this will happen one day with the current-gen consoles; with OnLive all you'll be left with is a worthless box that does nothing and an ugly, uncomfortable controller that doesn't work with anything else.
You are assuming that they will never extend the subscription service to PCs, that they will not be expanding it to include a lot more games and that there aren't more gamers already comfortable with "the cloud" than those that aren't.
This is only the initial beta test of the subscription service, it stands to reason that they are not testing the marketability of the product (though I'm sure that's part of it), they are focusing on the technical aspects. Once those are ironed out, they are just as likely to offer it to the larger OnLive membership as they are to leave only on the "console". The entire OnLive game library is not all that large to begin with, but they already have agreements with almost all the big publishers, so you know that library will be expanding. As for the collectors, I know far more gamers who buy a game, play it for a week or two, then trade it in toward credit on another game than those who lovingly treasure their old games. Even with whatever credit they might have gotten from a returned game, it is still waaaaay more expensive to keep buying and trading in that it would be to pay OnLive $10 a month to play whatever they want on the service.
