Made my first, small, unreal 4 game. A Hanoi Tower

looks good and i agree its good to start off small by making a project from start to finish so you can go through all the steps and see what it takes (pre-production, prototype, creation, bug fixing, polishing, etc)

i also recommend participating in gamejams with a team, it will teach source control and coordination and honestly its a ton of fun!

keep it up!
