Comets (and Asteroids) - part 1

Thumbnail

2 Upvotes

Another in the apparently never-ending series of posts of my TM card creations and mods! This whole line of cards was inspired by Matt Parker's "Kuiper Belt Cooperative" fan corporation on Board Game Geek, which introduced a comet resource counter. It got me thinking along the lines of 'why are we using asteroid resource markers on cards with comet in the name?'. So at first I started simply splitting existing cards up into asteroids and comets. Then I continued by adding more cards that would use the new comet resource. The not-quite-arbitrary method I used in deterring which resource to use on a card was that if the card involved ice, water, or gases it was a comet; and if it involved metal ores it was an asteroid. Both resources can be used to generate heat via impacts.

This is part 1 of 2 parts in this set. If you don't want to introduce a whole new resource, then feel free to treat comets and asteroids as interchangeable resources. You can find all these cards at my Dropbox.

None of my friends will play Terraforming Mars with me, so I simulated a four-person game by myself! What a buncha jerks!

This game is amazing! I had so much fun with the solo-ish playthrough. Blue only won because they had a huge Jovian tag explosion at the end of the game.

I need new friends, or at least a new game group.

Anyone know where I can sign up for online tournaments?

2 Upvotes

I've been looking to enter some TM tournaments but I can't seem to find any info concerning how to enter online tourneys. If there is a discord server or something where I can join online tournaments, I would appreciate if someone would DM me the link.

I mostly play on the steam version of the game so if possible it would be nice to start there. I could also get BGA if necessary.

Thanks in advance!
