So that extra 20 dollars is all the difference between locating original assets and rendering at a new resolution (no new content creation necessary), and building an entire new game from scratch, models, textures, CG background sets, writers, voice actors, programmers, directors, producers, etc etc etc... every pixel recreated.
You're mad. Daffy. Bonkers!
Have you ever posted an image on Facebook, and then someone asked for you to print that image out? Rather than taking that low res facebook image through instagram and applying various filters to make it look sharper, you'd go back to the original image file, and export an image at a higher resolution. It's simple. You don't have to re-shoot the photo. You don't need to find the location, attempt to emulate the lighting, call everyone to the location who appeared in the photo originally... no.. You just open the original photo file in MS paint and save it out bigger.
That's basically what they need to do.
They don't need to make a whole new game.
At 40 bucks and let's just say a very meager 70,000 sales, digitally, that's $2,800,000.
Is there not enough profit in there to pay the two or three dudes who just need to take original files and export them at higher resolutions?
Again, that's absolutely nothing like creating an entire game from scratch.
