I'm not being obtuse at all, the single sign on is would just be one, tiny integration point that would need to happen, just like Netflix/Qwikster. You would have to handle user reviews, game shelves, migrating games from one site to another, and a whole host of other issues. By the time you've added all those integration points, it amounts to nearly the same website (since the core functionality of both websites is the exact same thing).
You're arguing that all that's needed is single sign on to make going between the 2 sites not suck ass and that quite simply isn't true. Most of the GOG userbase will use this new feature, spinning it off into a separate site makes no sense whatsoever when the functionality of the two sites remain the same.
I see why you're concerned about the community here, it's a great community, but 1) you're jumping the gun and making a lot of assumptions, and 2) you're proposed remedy simply amounts to poor usability and poor usability is always bad for business.
You're completely missing the point. If you're going to argue that you're not being obtuse it would be nice if you could at least accurately summarize my position.
And no, I'm not jumping the gun on this one. People who ignore my predictions tend to live to regret it. I'm not an oracle and I'm not perfect, but there's a hell of a lot of downside to this, far more than any small upside could possible bring.
Poor usability is one thing, having a unified log in is hardly poor usability, if that were the case you wouldn't see it popping up pretty much everywhere. Moreover people wouldn't be requesting that sites be added to the system. In this case, most people are probably not even going to notice that there's a separate store. And they won't notice because they're not interested in retro gaming or they aren't interested in new games.
When it comes down to it, having a site that's chocked full of titles isn't good for usability either. If you've ever read up on behavioral economics you'd know exactly what I mean. You can very easily wind up with the Parodox of Choice where sales actually go down because the consumers have too many options.
Plus, by separating the sites you don't have to worry as much about discount fatigue or having promotions that coincide with each other.
And you miss out on all the synergy that goes with having them together, including leveraging GOG's current position to make the new game sales a massive success and forcing publishers' hands into accepting the GOG way of doing things (just as Amazon.com managed to do with the big music labels, even forcing the king of digital music sales, iTunes to change its tune).
I didn't say single sign on was bad, I only said it wasn't the only integration point.
Do I have 2 shelves if I use both sites?
What happens when the GOG site gets a game, does it disappear from new-GOG? Apparently I'll have an account on both GOG sites (single sign on and all), will my shelf have at GOG suddenly acquire my new-GOG game?
What if I review a game on new-GOG, do I have to go review the same game at GOG?
What if I post a topic in a game forum at new-GOG, will the people in the same game's forum on GOG see it or be able to reply?
What if I rate a game on GOG, will the (potential) suggestion feature on new-GOG take it into account when recommending me games (Steam recommends games based on your play habits, does it not?)?
I doubt I've even hit half of the potential integration points that would have to be designed and implemented in some manner to make the two site idea work.
You're posting theoretical problems, some of which may actually end up being a problem, but it certainly isn't a forgone conclusion and all of these issues can be addressed. There's hugely successful marketplaces right now that address them all right now, in fact. As well, you seem to be ignoring the massive potential for success and the fact that most people here would love a way to buy new games DRM free, we've been begging for it for years, in fact. I'm here because I can get games DRM free and support values that are important to me. GOG offering new games in no way has to detract from that.
