Star Citizen

Squadron 42, to my knowledge, is much closer to it's release than Star Citizen as an MMO. I suspect we'll be waiting until 2028 at earliest for either, but Squadron has a chance at releasing by then, late as ever but at least passable (and hopefully not a fixer-upper like NMS or Cyberpunk were) and possibly benefiting from it's age, but don't expect groundbreaking graphics as the games that have aimed for such since the release cycle of games in general hit the 10 year mark.

Star Citizen will always be a living project as long as it exists, but Squadron 42 will be more in line with people's expectations. Remember, GTA V started development before GTA IV was released, GTA VI has likely been in development just as long as CIG as a company has existed.
