[quote=“Wanderer, post:25, topic:8058”]There’s ONE way of doing an endgame and keeping Cataclysm open-world: doing an endgame that doesn’t end anything, but can be considered an ending.
It’s the method used both in Minecraft and EVO: Search For Eden(SNES game, recommend it). In both, you have paths that take you to sort of an ending. In Minecraft, going to the End and fighting the Ender Dragon; in EVO… i won’t spoil, but it’s a choice, not a battle.
In both cases, you can keep playing after the endgame, and nothing changed because of the ending. Killing the Ender Dragon doesn’t change anything in the Minecraft world, let’s say… joining with the sharks and dominating the prehistorical oceans in EVO shows you an ending and throws you back to before that choice, making it effectless, UNLESS you want an ending to your story, in that case, it’s a good point to consider it “ended” and leave it.[/quote]
Had considered that for the Mycus. In a funk at the moment so not much getting done. 
EVO has those as bad endings–there’s a final endgame, too. Agreed that it’s a nifty game but cartridge is probably the most expensive I’ve ever seen, at $120 or so on resale.
