It's just my perception of how powerful they are in a competent player's hands...I just wanted to start the discussion. I'm not ready to write an essay on each race.
Lol, I was going to reply to this post but then my thought was "if I cannot write a reasonable impression on playing each race, I really shouldn't be chiming in" hah.
I would rank criteria something like this:
- Outright faction strength.
- Ease of execution/play.
- Faction Nimbleness, ability to counterplay.
A lot of what you listed fits this mold. Mimot just getting flat-out double ships is strong (1), easy to figure out how to take advantage of (2), doesn't present any real downsides (3), and makes you feel like you're breeding like rabbits (4).
Whereas Drengin (for which I am about to start a SP game) have 1 (they're assholes) & 2 (just build a lot of ships and start attacking ppl), but have definite weaknesses in that influence and diplo are pretty solid counters to their playstyle (3). But they are Fun (4).
Of note, I included "Fun" because if a player gets "into" playing a civ, and has a good time, it's more intuitive how to play to their strengths (and will also increase a player's subjective ranking of how "good" said civ is).
My off the cuff observations is that the civs are similarly matched, but a couple could use some boosts. Xeloxi and Iconians rank at the bottom of your list. Xeloxi are underwelming to play (I wrote a longform observation on this (in so many words)) and never seem to do particularly well as an enemy AI. And the Iconians (whom I have no yet played) never seem to be very successful as an AI. So I agree that they're the lowest tier, just at face value. Navigators just need some AI love. Humans are exploiting their latient abilities like crazy, but the AI isn't good at exploiting them, at face value also.
It'll be interesting to see how this list comes along. I'd actually like to combine your question with another one: what is your favorite faction to play? Because I feel like this is actually at least as (if not moreso) important.
League of Legends:
Who is the strongest champ?: der... idk, LeBlanc?
Who is your favorite champ?: Teemo!
I rest my case!
edit: re-looking at your list. In my last longform game, the Terran Resistance went toe-to-toe with the Mimot all game with a little free-tech-help from yours truely (the Yor) and kept them in check all game - so they're definitely not weak. I'm no f***ing Terran player, but both Terran counter-play & balanced abilities are not to be underestimated. Terrans will hard-run the game if they get a strong edge.
Similarly I started a MP game tonight as the Manti. <50 turns in, they may seem like whiny bitches complaining about their lost eggs or whatever, but their recent buffs (every commander ship can survey!!!) are no joke, they hella' strong out of the gate. Depending upon how far we get on our MP game I'll do a writeup of the 0.90 Manti, but I'm not disappointed early game by any stretch of the imagination. MP isn't the best medium for assessing balance (since we cheat and trade each other free techs/stuff), but it should be enough to have an opinion. My opinion already is that they're no pushovers or slouches. My "go big or go home" is already that they're good, and should start with all enemy homeplanet locations and planet scanning should always cost a flat 1 prod.
It's an interesting question for sure Slarj (sp? sorry I cannot for the life of me ever remember your damn screen name (also you need to get yourself on the GC discord!!!)), but the beta changes really moving too fast to have a good handle on your question/ranking...
edit2: Yor are S tier on 1 & 2, (4 is subjective (is building rather than "free" pop really fun??)), but are at serious risk to good counterplay (like the Drengin are), but primarily early-game counterplay, they're not as strong an S-tier candidate than the Mimot are (the Mimot SHOULD NOT BE NERFED, but rather are an example of just giving a good strong straightforward mechanic to that works well - they are a model for how civs should be constructed IMHO obviously). My biggest question is: are any of the factions unplayable due to intrinsic crapiness? I need to play the Iconians, but I'd potentially put Iconians, Xeloxi, and Torian on watch for this issue.
