I'm drunk (a bit), but that is not the reason nor the excuse for this post, although it might be the trigger. What I'm writing here is what I think all the time.
In no particular order:
Geoff the Medio: I've come to love (very quickly) your succinct and concise (just one synonym is not enough) answers. If all people in Internet were like you, Google would expend way less energy than its current 8 TWh/year and the environment would be less damaged. Current mass extinction would be less massive! And then there is your huge and skilful dedication
Vezzra: your social skills just astonish me. Constantly. When I first registered in this forum, my prime leitmotiv came from my admiration to how sensible, prudent and simpatico you were towards anyone, no matter what. You seem to be immune to tiring people (I really envy that).
Dilvish: I love you too! No matter how long and overly explanatory are your posts
We know I've reacted rather overemotionally to some of your answers, and yet that does not make me appreciate you any less. Thank you very much for all the times the AI has kicked my ass.Morlic: That (the AI kicking my ass) goes for you as well. I take a bow for you too.
Cjkjvfnby: And for you! Any time I wonder if I could help in the AI development and I take a look into the code I think "wow, this is too big for me".
Adrian_broher: I've learnt some very useful Linux command-line stuff from you. I'm sad of the way you went away from FO, but your work here will never be forgotten (at least as long as Internet does keep running, in the long run we all will be forgotten, here and in real live, but you get my point).
MatGB: You are another role model. From zero programming skills to awesome FOCS developing in less than a year, and for several years! And without any of the sarcasm that make famous English (from England) people (that is a joke, I love Britons too!). I wish you'd still be here, among us, in this forum, in this lovely game, bringing in some badly needed balancing.
LGM-Doyle: You did like some of my ideas in the past. That made me feel proud. And more important, you are another of the developers that is helping FO be a reality. Thank you.
Ophiuchus: Hell, dude, your dedication, your kindness and your skills are also something that we all should follow and imitate. BTW, didn't you have a child that was going to abduct you?
I'm glad to know that parenthood is leaving you some time for FO (or at least that is what I heart-fully expect). Jaumito: Great species ideas and implementations, incredible sense of humour, and a nick that makes me constantly wonder if you are French and/or Catalonian (or something else... maybe otherworldly ¬¬). I really lament not having (yet) played against you, 'cause that would for sure make my mind blow up. Your only "flaw" is that you don't submit your awesome species as PRs to GitHub and I have to copy your files myself
Kirkkitone: One of the elders! And still alive! (in the forum). I bow my head!
O01eg: I'm really running out of words. Keep up your greatly appreciated job with the public multiplayer server.
dbenage-cx, The Silent One, labgnome: OMG! I'm really running out of words and compliments, and I can't just repeat myself! (anymore). You're not only contributors to FO but nice and helpful forum users that help lost players like me to solve their issues. Thank you! Please forgive me for not dedicating separate lines for each of you.
Tyreth, tzlane, Aquitaine, Impaler, pd, eleazar, Bigjoe5, Mitten.O, Ouaz, and many more that no longer frequent this forum but have made this game possible. I haven't met any of you (well, some of you have made some brief incursions in the forum since I first joined) but you have all my admiration and gratefulness for your contributions.
And for all the players (actual contributors to the code and design or not), current and past, that have put their two (thousand) cents here in the forum, defaultuser, EricF, em3, alleryn... I see you! It's just that I can't name all of you.
Special mention to Voker57, you are evil (like me), but in the good way. Maybe, better said, you are acid, and I do enjoy that. With this post of yours I was laughing for like two hours straight, and then I got stiffs for two days. I just reread it and again I can't stop laughing.
Edit:
Bestary!: Your lovely species drawings are a great contribution. Keep up with the good job, and I hope you'll get time and strength to do more.
Its a shame I didn't add you in the first place. And I don't discard finding more gruesome oversights of great contributors.
Kudos for all of you!!
Hmmmm... Now I'm feeling bad for the possible awkward comparisons that some could be reading between the lines. I just love all of you!
PS: bear my English and the probably mix of American and British I'm doing, I must trust my browser suggestions.
(Although I have to admit it sometimes baffles me how people perceive me - I see myself as much more "normal" or "average"
