I recently participated in the Unreal Game Jam with my team of three people. We made a game called EAT
First two days I was deep into making music with Reason for the game but after that I exchanged roles with our main programmer and had an opportunity to sink my teeth into blueprints. Suffice to say this course helped a lot.
The game was ok , obviously a ton of room for improvements and its problems quite obvious.
The experience was awesome , though we had some intense fights with one of the members of team (in the end I was proven right for many of the things I was complaining about) , nevertheless every single member did his best and we fully commited to the effort and tried to work as a team. I learned a lot of things and at last I made my first game
Highly recommended to give it a try even if you are like me and have little clue about Unreal.
