On AG2, there is a little section of text under a user's name if they submit a game that says "view all games by this author". My idea is that in AG3, you automatically other games by the author at the bottom of the page.
What exactly are you trying to say? Are you talking about viewing the games on their profile page or while playing the game? If it's the first one - I just went to a Developer's profile page on AG3 - can't see any games. However, it's still in Beta phase - maybe they'll add the games on their profile page later on. If it's the second one - you can scroll down, see the author then see the games while playing one of them.
But what if they have a lot of games, like John, wouldn't the page be really long?
I think that they can put into it the best games or casual games.. (better casual) just to watch what type of games the creator creates
Or another idea is that the creator select the games that he want the people watch much more than the others (sorry about the bad english... i'm italian and i didn't study english so much )
If a developer has a lot of games, we'll "aginate" it with a 'load more' button, or take you to a page where you can see all of them in one shot, similar to how AG2 works.
