One game design philosophy I’ve started to ponder is the “crunch-optional” philosophy – that is, the amount of crunch (e.g., the straight mechanics, rules, and numbers) one experiences from a game is based only on player investment. Those who wish to simply sit down and enjoy the game only need the base mechanics, while those who want to delve into the meat of a game have the option to explore the different rules and subsystems. Most importantly, however, is that players who do decide to “do their homework” and explore the crunch of a game are not objectively superior to those who did not – system mastery does not make player skill irrelevant, it just allows those who are interested to find more fulfillment in the rules.





Enter Traveller



I believe Traveller does this well (at least, the versions I’m familiar with; I have only played Mongoose Trav 1e and 2e, and am nominally familiar with Classic Trav), and this is why I play it frequently with both people who are new to RPGs and seasoned players.

Introducing new players to Traveller usually goes a little bit like this:





1. Send them to Send them to this character generation website and explain in 5 mins what each attribute does, what the lifepath process is like, and how they will interact with it through the website. (This tends to be very intuitive for most people – when you automate the process and simply leave the player to make decisions, it goes very quickly.)

2. When they finish, help them output their character sheet into something they can read easily and do finishing touches like picking benefits, purchasing equipment, party skill packs and finalizing character traits/background. (takes 5 mins usually – a character sheet can easily fit on an index card, and the lifepath process creates a backstory as you play the character creation minigame) When they finish, help them output their character sheet into something they can read easily and do finishing touches like picking benefits, purchasing equipment, party skill packs and finalizing character traits/background.

3. Begin playing the game. When the first time they need to make a skill check arises, simply explain that they roll two 6-sided dice and add their attribute modifier and skill level. Higher is better. (this takes less than a minute to explain). Begin playing the game.

4. Congrats! You are playing Traveller. Any other mechanics (combat rules, HP/damage, ship combat, etc.) are introduced as they come, and at their core base themselves off of the 2d6+attribute+skill mechanic. Congrats!

Total time to get started – about 15 minutes, in my experience.





This level of engagement is more than sufficient for most people I play with, and the simple mechanics tends to lend itself very well to OSR-style play – that is, players tend to utilize creativity and problem solving to solve issues.





(Tangent: I wish Traveller was discussed more in the OSR-spheres of the web, as I think it’s a great example of the philosophy in action. Alas.)





It's rumoured that Firefly was inspired by a game of Traveller Joss Whedon played in college.

Sure, these can create characters who are richer/have more connections/tougher in combat than other characters, but I’ve rarely found that to be too much of an issue – my campaigns tend to have enough of a mix between combat, exploration, trade, and political and social situations that characters who excel in one specific area don’t overshadow those who don’t, and interplay between Law Levels on different planets and the high-lethality of the combat system prevents those with better combat skills and gear from completely overshadowing those without, as combat is rarely the best way to solve your issues.





- Players who want to buy vehicles and starships/start out a campaign with one can just crack open a book and choose what looks best to them.

Players might design ships that are better optimized than the ones in the core book. If so, good for them! They deserve to be rewarded for good engineering.





Players might also design ships that have all the bells and whistles and can take on any system defense boat they encounter. If so, it’s going to be prohibitively expensive, and governments are going to be suspicious why a pocket warship is frequenting their space lanes (plus, governments have much more money to spend on a naval budget than even the wealthiest players…)

Most trade situations in my campaign end up like this, but with more guns

Heaven and Earth is my favorite world creation tool - I highly recommend it





Of course, what largely contributes to this is the ease that Traveller’s subsystems can be automated and the wealth of resources available online for GMs and players (One needs to look no further than the wonderful Traveller Tools created by Grauenwolf to find most everything you need to run the game), and you’d be right, it helps a lot. That’s the power of a small but dedicated community right there.





Traveller is definitely not perfect in this regard – for example, in both Mongoose Traveller 1e and 2e, the ship combat rules could be improved for both those who wanted low-crunch and high-crunch options. As they stand, they require a bit too much investment for new players, and lack a variety of tactical options for players seeking high crunch. Someday I’ll think of an alternative, if I get around to it.















In the end, all you need to do is roll 2d6 and play the game.

I’ve spent hours thinking of and writing Traveller scenarios with custom ships, fleshed out NPCs, and in-depth planets and systems. I’ve also run sessions where literally nothing has been prepared beforehand and everything was improvised. This crunch-optional game design lets both my players and myself prepare just as much or as little as we want, yet have good rewarding games.
