The Downtime rules are only 3 pages and mechanically consist of a single Extended Action that spans the period between Episodes. Yet, they accomplish a lot with very little. With one Test you can repair your robot, spy on the enemy or write a book that connects with thousands all over the world and makes you famous. The mechanic helps with...

For today we've got a grab-bag of all the Operations mechanics leftovers, totaling 6 different subjects. That's a lot! So without further ado, let's get started.
Terrain
Given that the game plays without maps, you'd think that there wouldn't be Terrain rules, or that they'd be barely relevant, and I would be lying if I said t...

In BCG there are 10 general Action types, not counting things like Combine, Restoration or Lightspeed Assault that are abilities which are their own Actions to use. Meanwhile in BCS there's 5 Primary Actions and 11 Secondary Actions, which can be combined a number of ways, giving you a ton more options every Turn.
While there's some ...

The rules for Operations are more than twice longer than those for Intermissions so we're splitting them into not two but THREE updates, because there's THAT MUCH to talk about here. Without further ado, let's get started.
Operation Structure
For the first time in many editions and updates, the Operation Structure is in two-column ...

Intermissions are a rather large part of the game. Often, the longest part of the game. They've always been rather simple on the mechanical side though, and BCS doesn't change that. It does improve how you play them, though.
The general structure of Intermissions is the same. You roleplay until you run into some kind of conflict, at which ...

A.K.A. "The rest of the general rules overview."
Pilot Levels
Pilot Levels, renamed from Power Levels, now have a larger mechanical impact than they used to. Each Pilot Level offers 1 Ace Trick, 1 Ace Perk and a +1 to all Tests. With this, PL makes pilots switching mechs feel like you actually get to carry over your talents from on...

The Core Mechanic
The most important change to how BCS works compared to BCG, along with the mapless play, is the new core mechanic. From Monsterpunk I learned that I strongly prefer degrees of success/failure to binary pass/fail resolution systems. However, BCS is a little bit different compared to other systems with degrees of success/...

I'm starting a new series where I'll be going in depth on the design of BCS, in the vein of the old BCG Restrospective, but instead of doing it for a finished game it's for one that is still in development instead.
We'll be going in the order that the content is presented in v0.1b. Because it's a beta, some aspects of the game may ch...

But I haven't had the time to write something this month. I've been thinking of going over all the mechanics in BCS a la the old retrospective series but the stars have been aligned in the opposite direction of me sitting down to write for a while. We'll get started on it next month, hopefully the beginning of next year is a little more helpful ...

Hello friends, rivals and assorted gentlepeople, don't mind me, I'm just going to drop the public beta of a whole new system at the same time that I'm announcing it.

The thing I originally was going to upload this month could benefit from a few more days of prepwork, so in lieu of it I'm going to do something related, but a little bit different from the usual. In the vein of blog posts of old, and particularly of the BCG Retrospective, I'm gonna do a bit of game design chat, talk about things that worked as ...

Barring any unforeseen bursts of sudden inspiration accompanied by a notable fiscal irresponsibility, this is the last art update for BC79. What could still happen is that I'll make a print version, which is enough of a pain and far removed enough from the design process that it's not something I'm interested in doing at the moment.
Anyway...

The anthology is finished! It's currently sitting at 70 pages and 6 Episodes. I'm gonna take another month or two for the editing and proofreading process, and also to wait for art. By the way, the anthology has a name now: Battle Century 0079, or BC79 for short, named after the year the anthology takes place in.

Work on the anthology continues. One of the highlights of doing this kind of project, at least for my personal sensibilities, is that I get to make custom mechanics. Take these three Features, for example:

I've been slowly chugging at the Campaign Module. However, I realized it was being harder than expected, and that was early while I was still writing the simpler Episodes. Worse, a part of me kept saying it needed to be longer and have more Episodes, for pacing reasons, you see.
The project was both growing out of control and lacking...

One of the coolest things about publishing your own games, is that the homebrew content you make for a specific campaign is only an editing pass or two away from becoming official content.
The Gemini System was originally going to just be a variant of the Allied Reinforcement rules, but those rules didn't do everything I needed them to do....

I wanted to show at least a new mechanic for the campaign I have almost finished, but I lost a hard drive to a power outage two days ago and it was the boot drive, so I spent an entire day getting the ex-slave drive in working order and that really took the wind out of my sails s...

So last month I promised a campaign scenario. Here's some numbers to give you an impression of what that'll be like:
- 9 Episodes. Each Episode consists of a short Intermission, an Operation, and a short optional post-Intermission Scene.
- 6 Introductory pages. If you've read Any Oasis in a Desert, the Monsterpunk cam...

Whatever I make next for the game will be free. Don't expec...

"No news is good news" goes the saying, supposedly coined by James I of England.
Clearly the king never felt obligated to give other people progress reports.

While all the new art is a great addition, the best thing about the decision to take most of the year to upgrade the book is just how many errors in the text I've managed to fix. Eight months, three game updates and two sets of proofreaders later, I'm still finding typos, double spaces between words, and the like.

Exemplar Themes are for characters who represent an ideal, often gaining power from it, like GaoGaiGar's Guy Shishio whose G-Stone is powered by courage. These often work best when there's multiple characters in the same group standin...
