I think it would be an amazing implementation for the endgame when the game goes gold.
In the dev livestream they were talking about meeting the duke and what not, being able to leave the planet and go to a government safe zone on a different planet would be amazing.
It would be rather interesting since the game Outriders was based on resources running out and they had to go to a completely different planet which had earth-like resources to rebuild.
So it wouldn't be ENTIRELY impossible the devs have an endgame (or modders) that the player leaves the planet in a cutscene to live on another one. Just unlikely, but a genuinely good concept in endgame terms.
I would hate this for several reasons. For one, I imagine something like this would be almost impossible for MP. For two, I would hate to spend countless hours gathering weapons/tools/resources/skill pts to build a base only to find out I completed the game before it's even finished. And instead of being able to kick back and admire hours of work I'm suddenly taken to a final cut-scene, and that's it....it's over. That would drive me nuts.
Most importantly, there's already an "end game" (indestructible base, ton of resources, skill pts make you a super human fitted with the best weapons/tools/armor, etc). The difference between this and your suggestion is that it's up to the user to determine when the game is finally over, as opposed to being forced. I personally like having options and flexibility.
Yes, the game becomes boring after you reach a certain point, but there are literally dozens of different ways to extend the gameplay by making it harder to reach the "end game" thru different options, mods, restricting yourself to a set of rules, a little of each, overhaul mods, etc. The options are virtually endless. And from what I understand, the vanilla settings are going to be even more flexible in A20.
For example, in SP, the game is over me after about 30 days on default settings, but I can change this to make games last 90+ days. I'm currently playing SP vanilla with these settings and restrictions..... I'm on day 42 and still no where close to being finished. It took me 20ish days just to get a damn bicycle.
-- Kinggen RGW 6k map w/ only 2 traders + 3 mods (larger wandering hordes/increased zombie spawn/MD 500 heli)
--Permadeath
--16 hr + 90 min days + max 3 land claim blocks
-- 64 Z's + Warrior (sprint day, nightmare for everything else)
-- BM every 4 days w/ 2 day range + no warning
-- 25% XP and loot, resources 50%, no air drops, no loot respawn
-- No starting skill pts after the tutorial (xml edit)
-- Have to max out one entire skill tree at a time before choosing another
(ex. Everything under Strength has to be maxed out before unlocking anything under intelect or agility, and so forth)
These minor changes alone prolong the game for me. The new POIs are going to make it even more interesting.
