Does anybody actually want to play these procedural generation tech demos? Maybe it's just me, but I feel like this market is becoming oversaturated for the sake of a vastly exaggerated audience that only seems to be there due to Star Citizen's absurd amount of backer funding. The thing they've gotten wrong though, at least from my perspective, is that people don't really want space sims, they just want Star Citizen. If people actually wanted more space sims, I'm guessing X3 would've gotten huge critical acclaim and would be worth trillions of dollars by now, and that Eve Online (popular as it is) wouldn't have the "niche" reputation that it currently has.
When I think of a space sim I think of X3 or Freelancer. I think of games with handcrafted worlds that feature developed cultures, architectural styles, and setpieces, whose narratives and experiences within them all derive from PvE/PvP or even EvE (haha) interaction within them. You can barely trust a person to craft a good setting, let alone a goddamn computer, and yet setting is most of the reason why these games stay with me.
Game mechanics in these are extremely important, as with all kinds of games, but I've noticed that when it comes to this genre, that these things are very, very easily let down by boring game worlds, which is the only thing procedural generation is going to give you unless your game is Dwarf Fortress. That’s because I just honestly don't see what's "addictive" about their overall gameplay formulae on its own. I can get addicted to the “clicking and loot” of Diablo but I can’t get enthralled within Albion Prelude’s (if we're being honest) dry as fuck gameplay unless it has an observable effect on a world that was created, at least initially, with some degree of heart, emotion, and creativity, that has actually attempted to make me give a shit about it.
