I can't decide which project to have a go at first?

There’s 4 projects for which I downloaded the files from Zenva.com last week, an Action RPG, an Idle Clicker, a Kart Racing game and something else, however I want to dive in and do a simple one first, but I can’t decide which one to do? I’m not really a Karting game fan so that’s possibly out.

Can you guys help me decide?

Obviously to pass the Degree I’d have to do all 4 eventually, but which one do I tackle first?

Alphabetical order.

The intro to game development one’s a Balloon popper I think, a bit like the old game called Pang.
