I want to start creating a very long project which i will work on and learn from. I've been making some basic games. Now i feel it's tine to step it up a notch.
My idéa is to create a 2.5d game such as Zelda. But i got stuck with viewport and world units. Since there is alot of viewports i can choose from and i've read what they offer. So what is the preferred viewport, dimension and world unit for a 2.5d rpg mobile/desktop game?
