I don't know, I think NMS is very ambitious and Sean would probably agree. You list a bunch of games that have tackled a few parts of what NMS does, but no one has done everything that Hello is trying to do with NMS and put it in one package. The proc gen systems for flora/fauna/planets in NMS alone are beyond the scale and complexity of similar games, and then you add NPC factions, a trading system with complex economy, a crafting system, simulated AI ecosystems, etc. etc. The breadth of systems in this game is not something we've seen before.
