Maybe we just need to start playing with ideas, a simple scroll routine, or animating elements that have ease in/out effects. Code copper effects, or replicate great effects we have seen in demos. I'd love to see coders write small bits of code and have other play, modify, suggest, and improve techniques.
Possibly for lots of people coding a full game could be too big a task. For me completing two games in the last few years "Dots Adventures" (PC, Mac, iOS) and Lunar Jetman" remake for PC were a lot of fun, in most part because of the people involved in those teams. It certainly required a lot of dedicated time and commitment, and yes it is possible with a full time job and family
I have to say that it is inspiring to see activity on other retro platforms such as the C64, Amstrad and ZX Spectrum.
