I've been playing this game for a week or two now. I haven't moved out of the Simulator since I want my code to be able to handle growing between rooms and fighting enemies, and I think that will be impossible to write in the live world since the tick speed is so slow.... That's actually my biggest factor in figuring out of I will continue playing this game or not. The tick speed means that once I enter the real game, development, debugging, and seeing your Screeps carry out the code will take forever. Also watching battles will be slow. I think the 5 ticks/s tick speed in the Sim is very nice. Even 2.5 ticks per second, but will I be able to stand 1 tick every 4 seconds? That's like 0.25 ticks / second...
