Microlite74 with 2D6?

I’ve been asked if I could create a version of M74 that used 2d6 instead of 1d20 so that the game could be played with six-sided dice only. This would be relatively easy to do. For example, the primary die roll would be 2d6 + modifiers with an 8 or higher indicating success.

Here’s a combat example: a 3rd level Fighter attempting to hit a human bandit wearing light armor (+2 AC) would roll 2d6+1 (+2 for Physical Combat Bonus, + 1 for Fighter Bonus, -2 for opponents armor) and would hit on an 8 or higher. If the GM wanted to have keep the opponent’s armor secret, the player would not subtract the armor and would just call out the result which the GM would compare to 8 plus the opponent’s armor — equal or greater would be a hit.

Saving throws could work as they do now except that 2d6 would be rolled instead of a D20. DCs would have to be lowered however — exactly how much would require some testing. However, it might be better to redo the saving throw system to use the primary die roll mentioned above.

Other than a few minor details (like subtracting 10 from all the monster ACs), that’s probably all the major system changes needed for a 2d6 variant of Microlite74. However, it would be tempting to rewrite the game to make the gam a bit more 2d6-centric. For example, attributes could be rolled on 2d6. An alternate/optional spell-casting method could be added where spells do not cost HP, but require a success roll to fire (2d6 plus caster level/2 minus spell level with an 8 or higher meaning the spell was cast successfully). Etc.

I don’t see the need to produce an entire new version of M74 with just the basic changes needed to use 2d6 instead of a D20, although I might add a few paragraphs on how to do it to a future supplement. However, it might be fun to create a new game with the spells, monsters and style of M74 entirely based on a 2d6 system. I’ll have to think about this.

    Or do 2d10 and you don't have to change even that much… I've wanted to go 2d with D&D for a while to add a little less randomness to it…

    2d10 would certainly work, but wouldn't allow the game to be played with only the "standard" six-sided dice that almost everyone has. Even people who have never heard of roleplaying games often have some around the house.

  3. I started a project like this last summer with Microlite74 as a base. I opted for a Descending Armor Class as it was then usable with existing modules that I had stacked in the attic. Don't ask me why, but I stinking love 2d6 as a base for RPGs and it just feels so Retro that I find myself traveling back in time to a misspent youth.

    Here's a link to the PDF


    It still has a few kinks to be worked out, but it may save you some time if you'd like to use it to work from.

    Drop me an email and I'll send you the DOC file if you're interested.

  4. Randall–have you checked out Spellcraft & Swordplay? It's 2d6 only, based off of Chainmail and thus has a casting roll for Wizards as well.

    And I just can't stop thinking about doing 2d6 attributes as well.

    Homebrew2d6 is neat. It's not quite the way I'd do it as I prefer higher rolls being better, but it really is a cool system. I probably need to add an armor class conversion table to standard M74, too.

    I prefer higher is better because my player group in the early 80s had STRONG opinions on the issue. Very strong opinions. LOL.

    I have Spellcraft & Swordplay. It's a bit more complex than I'd like for a "Microlite" based game. However, I will have to take another look at its spell casting system if I decide to do a 2d6 game.

    This would be a great addition, especially for those of us looking to bring in new gamers. Being able to given them a ruleset that only uses stuff you can steal from the ubiquitous Monopoly or Yahtzee sets is great. As you point out while S&S can do it that's a more complex system.

    It would also fit well into my Harry Potter movie give away idea.

  8. @Randall–yeah, I didn't mean that S&S had already done the job; just that it might be resource for you.

    Why not 3d6 +bonuses vs ascending AC. Magic is 3d6 + level +bonuses vs 10 + spell level. Keep attributes at 3d6.
