I have read that consumers can read reviews, videos and try the game before buy it (a demo), but, you need to upload a COMPLETE game as project, so how a 'try' version can be downloaded by the consumers?.

Because, all approved games in XNA creators club are complete games, is this right?, and once the new service is available these games will be in Xbox Marketplace and will can be purchased by its price.

The Communtiy game Service will expose a .IsTrial flag which you can read in your game to determine if you are in trial mode or not.

The trials are time based - though right now we don't have details on what that time is. I seem to remember that once the time is up the game will exit... there are some feature requests for the game to be pre notified of this so that it won't be just an untidy end.

So you submit a complete game with a code path that can do wahtever it likes for trials. e.g. only let them play one level, let them play limited lives, not give them power ups... its up to you.

Thank you very much, really. But then, when a Premium user downloads the game, is complete or trial?, in trial maybe there is content you can't see for a complete review of the content (appropiate content for age rating).

AFAIK, the complete game is downloaded, but only the trial content is seen if you download it as a demo, just like regular Arcade games.

The content that a player sees depends on the developer.

When you download the game for review, I believe it's full (not trial). However, once the game has passed review, you can no longer download it, so you can't get "unlimited free games" by being a reviewer.

Its a good question... makes sense that the review download is the full version becuase of content hiding but there's been no confirmation of this.

Jon is right though that once the game is approved you can't download it any more though yes the reviewers could still use that copy - they need a paid CC membership and XNA Game Studio installed though which will deter most users. Since MS also change the Guid (I know they change it after submission - I wonder if they also change it after approval) the review copy won't be able to play network games with the version on XBLCG which is a bit of a restriction.

Hehe, there is confusion, but in any case I think there is no much problem as only some review users can have a copy of the game, that really doesn't affect to your number of copies to sell, and maybe is a reward for those who use their time making reviews.

There is only ever one version of your game. If you want to hide some options when running in trial mode, you can check the Guide.IsTrialMode property. Games are not required to check this at all, though. Even if you don't write any special code for this, you will still get a good trial mode experience, because the framework handles the most important things for you automatically.

For instance, we will enforce the time limit, and bring up a "hey, your free trial ran out - do you want to buy the game or quit?" screen when this runs out. So for most games that only care about the time limit, everything just works without them having to write any special code.

The only other limitation we enforce about trial mode games is they can't use networking. Again we enforce this for you: the gamer privilege for networking will appear as false when you are in trial mode, just the same as if they were a child or Silver account, and we'll throw an exception if you try to use networking while in trial mode. So again you don't have to write any special trial code for this: it will appear to your game exactly the same as any of the many other reasons networking might not be available (Silver account, child with parental controls set, etc).

For testing and reviewing your game before it is released to consumers, you have several options:

• In the Xbox UI, you have the option to launch the game in full or trial mode. Reviewers can use this to check whether it behaves differently in the two modes, and make sure both versions are sensible.
• You can use the Guide.SimulateTrialMode property to make it behave like trial mode is on, even when it really isn't - useful for dev testing if you want to debug a problem that only occurs in trial mode.
• If you call the Guide.ShowMarketplace API while running the game as a developer or reviewer, this obviously cannot really take you to Marketplace, since the game isn't up there yet - instead you get a "this is a simulation screen for testing - do you want to simulate purchasing it now?" message, and if you say yes, we'll switch you from trial mode to not trial mode.

Wow, what a COMPLETE information!, I think there is no more questions about this. Thanks for it.

If you're allowed to answer, will this screen be customizable by our game? For instance do we provide the background image for the framework or is it a generic buy screen?

It's a generic screen. I assume we'll have your game title in there, but you don't get to customize it. Presumably by that point they've already been playing the game for long enough to know what it is they're deciding whether to buy :-)

Also the time limit is per-run, so if they still aren't sure, they can always just quit out and launch the game again to play it for a second trial.

Both valid points, however my concern is that consumers are used to the XBLA experience where the buy screen has some customized display with a couple screenshots and maybe some bullet points of what they get by unlocking the full game. I think by not having that available for XBLCG it does us developers a great disservice because our consumers will not know why they should bother paying for our game unless we advertise that in-game. And if we're already doing it in-game, it defeats the generic buy screen. I bet it's too late, but I put up a Connect issue for this. :)
