Isotope is a 4-page post-apocalyptic RPG. When I read it, it looked like a simpler Apocalypse World to me. Easier to create characters, none of the playbooks, moves, and all that extra. I was reminded of Vincent Baker’s 2011 blog post Concentric Game Design. There, Vincent says that Apocalypse World has 4 layers of rules. The first layer has a few stats and uses 2d6: “On a 10+, the best happens. On a 7-9, it’s good but complicated. On a miss, it’s never nothing, it’s always something worse.” That’s basically what Isotope does.
There are four classes, human, mutant, wolfling and troll. Assign -1, 0, 1 and 2 to the four classes, get some perks, mutations and some equipment, go. It has an optional list of character names. We played for about 2½h. After the game, players said that they really enjoyed character creation. It was short and the two pages of classes, names, mutations and equipment provided all the setting information they needed and just enough complexity to have them pondering their choices without getting bogged down.
The rules being so short we ran into two issues. One player really wondered about gaining levels and hit-points. You basically have between seven and twelve hit-points. Roll a d6 for every level you have and pick the highest result, add six. You optionally reroll whenever you get to eat, drink and sleep and you reroll when you gain a level. I think I get it but something about how this was worded confused one of us, as I said.
The thing that confused me was how combat works if a creature has multiple attacks. The way I see it, combat means rolling 2d6 and adding appropriate numbers. On a 10+, you deal damage as per weapon. On a 7-9, you deal damage and you take damage, I guess? Not sure about this one. On a miss, you take damage. But then the rules say that monsters should have one to three attacks. How does that work? Just triple damage? Wow! Perhaps I should check Apocalypse World or Dungeon World.
The sample adventure provided was interesting but light on stats. As I said in another blog post, I like to believe in the independent existence of my game world. This means that I don’t like improvising monsters, traps and rewards on the spot. If I do, I feel like it’s me against the players instead of me acting as the impartial referee between the game world and the players. Improvising in this context often means adjusting the difficulty, being tempted by an imaginary arc of excitement, reducing player agency.

This is where I made a misake. I started with a few notes:
As the game went on, I added more:
It was quick to do, no problem. It just felt a bit weird to write these things down on the fly.
Figuring out which rooms contained useful loot was a similar problem. Was the big loot in the flooded room at the bottom? If so, what did it contain? What would be the big reward for successfully launching the rocket? Should I run it again, I would have to better prepare a few end scenarios so that I can push players towards one of these endings with appropriate closure as time starts running out. As it stands, the end was a bit flat.
So, next time: More prep!
As far as plot goes: the party got split towards the end. One managed to have the shadow dragon open the sarcophagus and so the character went exploring and found some valuable power tools to sell. The other characters found the map room and managed to set the intercontinental missile targeting system on a few cities by accident, but I decided that more was required to actually launch the rocket. We didn’t have the time, however, so we broke off saying that the delvers camping around the titan sarcophagus had finally caught up to what was happening and would start exploring the structure soon enough. The power tools where the only loot recovered.
We spent half an hour after the game talking about it, comparing it to Apocalypse World (which was deemed longer and harder to get into for little benefit), Lady Blackbird (which was deemed to promise better character development via keys and locked tags) and Traveller (which was deemed to similar in that character development basically meant the accumulation of gear and allies instead of powers).
I said I’d run a Lady Blackbird hack in two weeks time. Perhaps The Bugs of Venus? Then again, I like the original Lady Blackbird characters, I like the romantic angle, and I don’t have much experience in the military fiction genre, didn’t like Starship Troopers too much, don’t know whether I can recreate the Alien feel… We’ll see!
