Have you guys ever done game jams?
I do them periodically to keep my skills sharpened and to push myself to make quick release projects every so often.
Just in case if you don't know what a game jam is, it's a competition that puts a time limit on the making of a full game. Sometimes they are 24hr or 48hrs but the ones I like to join are usually 2 weeks to a month those feel more do able with a busy lifestyle!
If you never done one and are feeling up for a challenge give it a try!
