For Savage Worlds…
Ship combat is a major feature of many SF RPGs, and when I convert those to Savage Worlds, it’s one feature that doesn’t convert well. It’s also not a major part of my games, because my groups don’t enjoy it any more than they enjoy interstellar trade.
Historically I’ve addressed this by either not having space combat in my games, or by writing clunky, complex rules interfaces. But now there is a better way; the Savage Worlds Quick Combat rules.
All you need to know about the two opposing ships to use them is this: Is one side outclassed, or even massively outclassed? Follow the link and read the rules, you’ll see.
The only tweak I’d make is that the PC’s ship takes a Wound every time one of the PCs does, meaning that the ship ablates away faster than the characters, as is proper for a pulp story.
If there are more than one or two ships per side, you should really be using the Mass Battle rules anyway.
Have I missed anything, or is it really that simple?
