1. A made two games for the jam, both took about a weekend to finish. Runner for Love took more hours because I wanted to give it proper cyberpunk aesthetics and that took time. I Served a Crazy Emperor was easier, basically just some brushing up on my history and finding suitable mechanic.
2. I think I really need to decide what do I want something to look like before I start playing with graphic side of the thing. I spent much time redoing elements I've already done.
3. Deciding for simple mechanics is not easy : D I love one-pages and I've played many of them, but I have trouble deciding what mechanics will be the best for my game.
4. I didn't have the time yet, but I really want to try Hawker, Caveat Emptor and The Long March, and I'm sure I'l find more I like :)
