Again we roam to Gamma Terra and the Gamma World RPG – my favourite post-apocalyptic RPG of all time. At heart, I am a fan of the third edition of the game – it was the game that really implemented the rainbow result charts that were the rage in that era with results codes for every possible use… rolling for surprise? White means one thing, blue another, green another, etc. Same thing for just about every encounter, social roll, attack, and so on. Effectively it allows you to create mini-systems for every aspect of the game, while sticking to a single unified mechanic.
If I were to run a Gamma World campaign starting this weekend, I would be torn between third edition and the more easily understood fourth edition. Third edition was plagued by being rushed out the door at TSR – it had an errata booklet that adds all the material they supposedly edited out but forgot to edit out references to. Little things like price lists, and a working Plant Mutations section.
The d6s and percentile dice are back, and a mutant plant wanders in to town from the radioactive wastelands…
Third edition added a new plant type, symbiotic plants, but I always found the rules confusing as a teenager, and I don’t feel like trying to interpret them now – maybe I’ll try to make a symbiotic plant for my advanced GW3 NPC. For now I pull out the rules and decide on some baseline stats for a mutant thorn-apple bush. Obviously it will start with thorns and fruit, and I think that’s it. I might even omit the fruit if the thorns are too good of a mutation (but on review, decide the fruit stays). Juniper also starts with a free mobility mutation (I go with legs, because I want something vaguely humanoid in the end, not a gas-bag propelled thorny shrubbery… even though as soon as I wrote this I wanted to go back and restart the whole process to create exactly that), and d3 physical and mental mutations (1 physical, 2 mental).
Ability scores are determined as you would expect from the creators of D&D, 4d6-L with the usual 6 stats to roll them for. The fun part of course is the random mutations that can define a character, or leave him a ruined husk on the radioactive wasteland. What I end up with is a thorny walking bush who can read your mind and is a master merchant. An odd addition to any party.
