A light bot start with basic modular armour, a pair of roboports, a few bots, and equipment to power them.
Small changes concerning balance, gameplay, or graphics.
Armors or armor equipment.
Play it your way.
I have noticed a strange thing--we have 40 bots and 2 roboports--but only 20 bots are ever out at once.
In vanilla, the robot limit on a personal roboport is 10 bots. Hence the 20 limit with 2 of them. So think of the remaining 20 as spare.
The real reason I added 40 was because, some of the most popular overhaul mods increase the robot limit per personal roboport to 20.
