  • Getting old is hard
    For all intents and purposes the game is already released. They are basically advertising it as a released game (see if you can find the single reference to "alpha" here: https://robertsspaceindustries.com/star-citizen), in game purchases have been live for years, you can grind and save your progress etc etc. It's a live service game just like any other, practically speaking.

  • I love this game so much. My only wish is that it was an easier sell.

  • STAR-DP7P-GD4P for 5,000 UEC [+More, see post]
    There are two components to Cloud Imperium Games' (CIG) project. Star Citizen is the MMO component, a first-person experience in a simulated 30th-century universe. Squadron 42 is the single-player component, a story-driven campaign where you enlist as a UEE Navy combat pilot. Our current understanding is you will be given the option of having your Squadron 42 character, who musters out of the Navy at the... Source: 12 months ago
  • Can we stop and clarify what "alpha" means real quick?
    Just go to https://robertsspaceindustries.com/star-citizen and it's clear as day. The whole thing is written in the present tense, with big play now buttons and like 2 small disclaimers saying "Note: Star Citizen Alpha 3.18 is currently available to download and play. Additional features and updates will be released as they are developed." as the only disclaimer. Literally anybody not intimately familiar with Star... Source: about 1 year ago

  • My 9 year old nephews drawing of stars
    I think Celestia could be a good one. I also thought about SpaceEngine, but AFAIK it was kind of terrible at generating realistic planetary systems, among other things (pricey, huge, etc.). Source: about 1 year ago
  • What are the best resources to explore space from my computer?
    Celestia was something I played with before. Pretty interesting. Source: over 1 year ago
  • Lunar Occultation of Mars
    Celestia looks as though it would do it. Source: over 1 year ago
  • Tips to visualize Apollo 17 trajectory
    I'm looking for data and software to visualize the Apollo 17 trajectory (especially the "powered descent", lunar rendezvous and entry). I'm thinking of using celestia. I'm look for a data tables as well (time stamp, position for each part of the stack). Any tips are appreciated. Source: over 1 year ago
  • Help rediscovering a certain night sky exploration program?
    Yes, that's Celestia most likely. I'm not sure it is still maintained though. Source: over 1 year ago
