I have both DLCs activated, that's not the point here. The point is whether you can play only 2016 version for all the new content when you are asked which version you want to play when launching the game.

2016 version seems to have some improvements to wallet system but the story is basically the same when compared to 2015 (or it seems to be, if someone knows about other differences post Kyoto, please let me know). 2016 version has some bonus love interest sights, not included in 2015. The games doesn't share savegame slots but they share read text for skipping function.

Well, so I tried running 2016 and then 2015 to compare it and seems both versions are basically same in terms of introduction and that 2016 includes even 2015 sights when you own both DLCs.

This is how the travel map looks when you got there:

If you choose 2015 (1.0.1) version when starting the game:

If you choose 2016 (1.0.2) version when starting the game:

In comparison the original game looked like this:

So it seems it's okay to play (latest) 2016 version only if you own both DLCs as it includes everything. It has all 2015 has to offer and more.

When you open the game, select the 2016 version. Because you have both expansions, all of the content in 2015, including CGs, can be found and read seamlessly in that version of the game. It sort of builds off one another, so if you have both packs, you'll be able to access both sets of content, including the content from the original game, in the same package.

Thanks for the answer, I was not sure at first as there are actually three instances of the game in the steam directory. But then again, it's only logical to run the latest 2016 version as it's the only one that has achievements.

Bumping this up to answer the questions for any new players as the basic game is now free.

Thank you for doing that. It's useful info.

Good if this post is in guide section so I don't need to search it up every time

Was about to ask about this but I found this post just now, thanks

Genuinely thanks for this, I found other threads with conflicting info but since you posted image proof of 2016 containing 2015 locations (Tokyo Skytree). It's 100% proven fact that we only need to play the 2016 version. (But have to buy both) DLCs.
