Right now this site is small so it's not a big deal, but based on my understanding of this post the system lends itself to abuse. Elo is based on a 0 sum system. When you beat someone, your elo goes up, theirs goes down. There is a reason for this design. If you have an elo floor, people can gain elo by beating opponents without their opponents losing elo. This means I could win an infinite number of games against my 100 elo friend without them ever losing a point, with me gaining the whole time. Again right now this doesn't matter, but if this site grows people will abuse it.

In addition, the system you have implemented means the first 100 points don't matter. Why not just start at 100?

The original system that starts at 1000 still prevents people from having a negative elo rating. If you are worried about new players, a 5 or 10 game grace period would give them time to learn the site without breaking the system.

I don't want to sound critical but the elo system as originally designed works well and has decades (in fact almost a century) of track record. I don't think there is a need to change it.

@Robert-Shepherd That's not how the rules regarding Lantids read. It specifically says "it does not count for any effects that relate to how many planet types or Gaia planets you have colonized". If it was meant to include gaia planet round scoring it should simple say "it does not count for any effects that relate to planet types or Gaia planets".

Edit: Upon further investigation, you are right. There is a lengthy discussion on a thread where the developer weighed in here https://boardgamegeek.com/thread/1875760/lantida-question/page/1 While the rulebook is effectively wrong (or ambiguous at best), apparently the intent is more clearly demonstrated on the Lantids board. The rules for this site should be clarified as we can't see the actual playboards.

@Babbuc49

From my perspective satellite scoring just doesn't add enough strategic interest for how complicated it ends up being. It ends up being some fiddly thing about manipulating the board in ways that are almost impossible for casual players to understand (blocking out one fed so you are forced to build satellites around it the long way etc). I have already found two bugs in how the online system handles satellite building in corner cases, but I'm hoping it will just be removed from the game so I don't have to explain them :)
