I wanted to try out Unreal Engine to see if I would like working with the engine or not. I created a very basic Tower Defense game just in 2 weeks. Even though the game turned out to be very basic and a bit buggy, I'm still surprised that I managed to create a complete game from the Start button all the way to the Game Over screen in just 2 weeks, and I will definitely keep learning the engine to create better games in shorter time.
