Yeah it's the proof of concept part that I'm struggling with. I'm asking myself, how would I actually do this? ... and coming up blank. I just don't think I have enough knowledge & experience yet. I've only made two very tiny games with Unity so far.
But yes you're right I'm not going to find a tutorial on how to make a post apocalyptic strategy farming game lol. But I'll find some on making a farming game, on certain strategy games and so on. I need to pick these apart and try to learn just enough that I can get started.
The patterns is something I really enjoy learning about actually. I have a few books on patterns and I suspect that I will I find myself coming back to them over time as I gain experience.
