I was inspired by games like Dwarf Fortress and the lesser known RimWorld Alpha, a grid-based game where the player manages AI colonists who collect resources and build items and defenses to combat invaders. I have previous experience with building 2D and 3D game engines, and I like to clone or at least emulate key gameplay found in both professional triple A classics and indie titles. It uses A* for pathfinding and Diamond Square, a recursive terrain generation algorithm similar to Perlin Noise, for terrain levels and gradients. Written in "pure" java with Processing for rendering.
