Due to many games getting significant expansions, I think there should be a way to sort between DLCs/Expansions of a game.

The Binding of Isaac: Rebirth is a great example here. This game has three seperate expansions (one of which is coming out next week). For some reason though, when selecting a game to stream there are only two options; The Binding of Isaac: Rebirth and The Binding of Isaac: Afterbirth.

Due to Twitch's name rules, the other expansion The Binding of Isaac: Afterbirth+ did not get a twitch game name. The final, biggest and most impactful expansion, The Binding of Isaac: Repentance, probably won't get one either, despite Afterbirth for some reason getting one when it is also an expansion.

Shouldn't only the Binding of Isaac: Rebirth be a game option? Why Afterbirth? If it is based on expansion size, should Repentance be a game stream option since it is by far the biggest expansion changes basically everything about Rebirth? This may seem mild but it can be very confusing for viewers when watching a game. They buy one product yet their favourite streamer is playing something much more grander than they purchased, due to Twitch stopping at Afterbirth and not including Repentance.

What I am proposing is a simple way that when selecting a game there is a selection box or something of the sort to indicate what Expansion if any is being played. It would make game selection for streamers and game searching easier for viewers, allowing them to get exactly what they want. It can also help with visibility leading to more purchases, supporting the developers themselves.

I guess this could complicate some things, but if all the expansions are still sorted into the category of the original game, it could keep the interface clean and easy to use.

This is of course a suggestion and a kind of messy one, but I think it could work out in the long run.
