So we ultimately already reached level 50+, killed everything, scavenged every single hole for collectibles and managed all settlements...

And...that's it?

I would love to see some end game content after campaign and all side quests...and maybe some sort of dungeons or raids wouldn't be a bad idea after all? Blizzard in their most recognized game in the world is managing this quite well, I wonder how would that fit into Fallout 4 universe.

Maybe melee combat arena as I mentioned in my earlier posts, similar to the Mad Max Beyond Thunderdome with 20 unique bosses each stronger than previous.

Raids that resets every 2-5 days with 10 legendary bosses that requires special tactics to kill for example certain weapon, killing adds in order and having small chance to drop unique powerful equipment and weapons.

I mean try it Bethesda, if people like it, it may prove something worthwhile when Fallout Online idea pops in.

But what would you guys personally see as a end game content that would constantly push you?

Factions have repeatable quests to clear out places. Enemies rescale and loot changes. Also about 20 settlements to build I think. Have to re roll the character or wait for dlc. I don't think Bethesda will ever put raids in. I wouldn't mind a super hardcoe arena also!

True endgame for Fallout and Elder Scrolls games is modding. Bethesda will provide their own official mods in the form of DLCs and modders will provide far more content. After all, some people have played Skyrim for thousands of hours and that is certainly not through official content.

Totaly agree with this I played skyrim for almost 6000 hours and would have stopped at 500 hours if it was'nt for mods

Yeah but how many hours did you play to get to this point? It's not an MMO. It's a single player game.

I am powerful enough to stand there taking shots and at the same time one shot everything with pistol. I am looking for some end game challenge, something what can one shot me if if i make a mistake and at the same time something difficult to kill but fun to engage with as well.
