This Darius collection has a shitty deal going on where you have to get the more expensive, limited edition to actually get all the games included, so it makes sense they want to capitalize on a selected group of enthusiasts that will pay for that version instead of making the full list of game widely available digitally. Pretty awful, yikes.
That's not the end of the bullshit -- you had to pre-order on Amazon Japan on Prime Day in order to get a download code for Sagaia (Game Boy) which is otherwise unavailable making the collection a bit more incomplete for everyone else.Holy crap, you weren't kidding. ¥16,800 for five additional games + physical extras.
That's downright diabolical. lol
I'm buying the special edition like a chump because I love shmups and Darius but the whole thing is pretty terrible, though unfortunately not without precedent.
