Unbounded Scrolling

Hello.

So far I can't really understand why would you use unbounded scrolling or not. It just disables layout limit so why not just increase the layout size instead?

Could someone with experience elaborate some pros and cons for a platformer game like Super Mario, Megaman, etc?

Thank you

Many games have infinite layouts. Endless runners like Flappy Bird, for example.

So that's why.

It just gives you more control. You probably won't know the exact dimensions of your level or room when you first start, and you might not like the rectangular shape or top-left orientation, so unbounded scrolling lets you change that. Personally, I like to set the bounds myself with 9-patches and a custom camera. This lets me build any kind of level I want, with any combination of shapes, in any orientation, and all I have to do is drag some objects around.
