If people are still interested in playing city builder games, I am in the middle of developing one right now. I cleared the CPU hurdle of path finding via developing my own algorithm ( old demo here: https://www.youtube.com/watch?v=7q0l87hwmkI ). Here I am pathing around 300,000 units to their own unique destinations.
Unfortunately I dont have a video update yet, but my game's graphics are now isometric (like SimCity).
I also take a little inspiration from The Sims in that the player will see the interior of the buildings so they can watch their citizens live their lives.
