Not my bag I'm afraid. I do have several ideas tucked away for future projects. I've got a rough design for one of which is set in quite a few British towns and cities with travel between them and several locations per town/city. Its going to be fairly massive and I'm dreading starting it. Its going to be an evade capture style where you can only spend so long in certain places before the hunters track you down. Think of the TV show 'Hunted' and you'll not be far off the mark.
My biggest problem is that I need a motivation to work on them. Life is a busy place for me and a game jam helps motivate me. I'm going to stick to entering now and again with mini adventures.
