Examples of sports, games, and/or gambling in your campaign. . .

Let's hear 'em. I'm very interested in knowing how you applied the Coda rules, altered them, or threw them out entirely.

Mostly we've used opposed tests for gambling. Basic skill rolls [Gaming (appropriate specialty)], and the like.

The Legacy's Tactical Officer, Douglas Painter, would be a rogue, con-man, and gambler if he weren't in Starfleet. And he is an expert at Texas Hold 'Em poker. So he has Gaming (Poker) as a skill at a pretty high level.

We've had people playing Tennis and Handball on the holodeck (using Sports (Tennis) or Sports (Handball) with Athletics affinity, and opposed tests), and even a round of pool in our TOS game (when the XO looks like Paul Newman he has to do a bit of hustling !).

BTW, we considered Pool/Billiards as a Gaming skill, and not a sport, even though it is more physically active than chess, or checkers, or playing cards.

It's not a sport, but several of the characters in my old campaign used to get together in the mess hall once a week for "20th/21st Century TV" nights. Their characters were big fans of science-fiction of that era, and used to watch:

Babylon 5
Stargate SG-1 and Atlantis
Farscape

And of course, they were all fans of a hugely popular TV franchise that started in the 1960s and ran for several years, then kicked off again 20-odd years later and ran for many more seasons. It detailed the exploits of the crew of a starship of exploration and research, which also assisted those in need and fought the good fight when necessary.

Of course, the series was called Galaxy Quest.

Many years back a player I had under the FASA system wrote into his backstory that he was his colony's champion at zero-g crown green bowling.
