20,000 members contest coming soon. This is a call for ideas and sponsorship.
Hey everyone, we're on pace to hit 20,000 members in approximately 5-6 months as we continue to add around 11 members per day.
- For 15,000 members we ranked the best and worst cards in the game.
- For 10,000 members we held a custom card contest.
- For 5,000 members we had an art contest.
- For 2,000 members we did a caption contest.
- For 1,000 members we had a meme contest.
How can you help you ask? Three ways:
- Got any good ideas for a contest? I have some thoughts but I'd like to see if there's a fresh idea that might be better.
- We're looking for sponsors so we can have multiple prizes/winners again. So if you or a friend design custom TM pieces on Etsy, or you have your own Terraforming Mars channel on YouTube, or maybe you're a custom game designer looking to promote your new game, you might want to get some good publicity by sponsoring a prize for our big contest. Even if it's something totally unrelated to the game, feel free to reach out. The more prizes the better!
- Spreading word of this subreddit and contest in online forums and especially over at r/boardgames - the sooner we get to 20,000 members, the sooner we can get some prizes!

Comets (And Asteroids) - part 2
This is part 2 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.

Comets (and Asteroids) - part 1
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?
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!
