A loose adaptation of ODnD realm rules for a scifi setting.

what @rsanford said is the jist of it. if you already know how advantage works, just ignore the bonus. Luck and its associated metacurrency is also a new mechanic, but can be derived the same way. when 6e says a characteristic, it's the lowest number of the 7e set.

This is what draws the line between a good game idea and a good story for me. The crux of the session should be player choice, and the consequences that come from it.

It gets pretty hairy when you start thinnking about it. A game designer has to draw lines somewhere.

The primary goal of suppressive fire is to allow move-and-fire actions like bounding overwatch or initial troop placement. Suppressive fire forces the enemy to take cover from the fire of group 1 while group 2 moves on the battlefield. How do you determine how much area a SF attack can cover? my rule of thumb for burst fire is that the targets must be within 3 hexes (~10m). SF doesn't require (much) aiming, and thus should be able to cover a larger area.

How do you handle it? Autofire rules mention it, but it's not defined as such. We can assume a contemporary or future setting. Here's how my group is handling it: Mooks under suppressive fire (SF) must go prone/take cover or take damage. Uses a full clip, can cover a large area of map with no chance to hit unless mooks don't dive. Anybody who doesn't have a name dies if hit. Only usable by weapons capable of burst fire.

Saucy, but he has a point. The Mythos as it was formed was a collaboration between the various writers of Weird Tales et al. Killing each other off in their stories, expanding and playing off of each other the same way a roleplaying group does. A genre is a set of conventions, mashing them up can be as much fun as playing them straight. The Cthulhu Invictus line should have some cool ideas for stuff to do in a Classical setting.

I was thinking of "facing" more than vector. A fighter, let's say, can reverse/adjust facing with very little thrust required and no resistance. Like in Babylon5/2000sBattlestar Galactica where they flip on a dime. As oppposed to naval combat where turning/facing is a big deal.

alright let's make some wild assumptions: Lasers do damage with heat, needing contact over duration to do significant burn. So you have to be close to keep contact. Railguns do instant kinetic damage, but because of their relatively slow speed have less range. Missiles/torpedoes do instant damage but have range limited by fuel. they can also be detected, so you can't shoot from too far away. what else ya got?

This is one of the most important parts of the puzzle to me. Yeah you can be a big damn hero, but a punk with an AR can still take you out. Changes the way that the players interact with the world.

matching speed is a matter of ship positioning and moves in the Chase system to stay within a certain Range matching V sounds like a white-knuckle mano-a-mano dogfighter pilot affair, and should be settled with an opposed Piloting roll. I can imagine a series of opposed Pilot checks determining attack and defense initiative in a fluid way. This sounds very interesting. Opposed checks between competent parties tends to end in a tie with both succeeding. Would this be the "even odds" situation, giving neither bonus nor penalty?

yeah, I have used Weapon Range to account for this. Of course the tungsten or iron ball fired by the railgun will continue moving indefinitely in the void, but the relatively low speed means it's only accurate within a certain range for a moving target. Missiles are another can of worms, still going back and forth on whether they should have movement and a presence on the battlemap, or to just keep it simple as an attack that can be dodged by the pilot.

How to use the existing chase rules in the black void of space, some ramblings: 1. There's no top speed in space, so the speed stat is not needed. Accel is king, perhaps mitigated by the mass carried if you want to get that crunchy. 2. No friction and preservation of momentum means no turning rules are needed, but the "moves" table in the chase section would be altered. 3. The Handling stat should determine the "class" of ship, and keep them in line performance-wise. 4. The abstract ranges are perfect for space battles, as the distances are usually too weird to imagine.

Rifts does it well, portals to the cowboy universe, alien planets, fantasy realms appear in all of the above, linking the worlds to each other.

why do I need the "slot" designation here? Don't magic points do the job better?
