The game is seriously popular tho.
I used a AI program to find yandere games, and most newer, and smaller, games do not show up because it has zero internet access --so someone took the time to feed the AI info on your game. Which is a good indication it's a good game. Or at least a popular one.
And I know it's a trilogy; Steam says so on my wishlist. lol
I never buy games outside of Steam, but I'll be waiting for the realize of the full game there.
I like to collect all the good games in one place when I can. ^_^
Releasing the games one by one on Steam could actually benefit you more than realising them together.
People who play a game and love it will always want more and more content.
Being able to buy a follow-up / related game with their beloved characters after finishing the first one, even if they have to wait for it to come out, is always going to be common.
I remember the lines for the World of Warcraft expansion packs, even AFTER they started to sell them online, because people wanted the new ones the second they dropped. lol
And I personally always end up buying DCL content for the games I love because I want the story to never end, after I first get the happy ending I want. (Using the word 'happy' loosely here, since I consider a romantic ending far better than any other ending in a yandere game.
Even if that means you end in the hospital horribly broken and the super-nice guy who's never hurt anyone tells you he's going on a killing spree to kill those who did that to you, or like one end in Particles of Reality when Sebastian pulls the plug on you in the hospital and kills himself to join you.
Although it's of course better if you both live and can be together. But not all games allow for such a super-happy ending.
...and that's not despite the fact that the guy is bat-crap crazy, but because of it. lol
I make no guarantees for my sanity. xD
