Limited Expansion

[Imuka]

Longer games are better imo. Eureka is busy work. Some people like busy work. I like games.

I have to highly dissagree with that.
What you say implies that the Value of Media is equal to the Time invested into it.

Going from that we could say that "Star Wars: The last Jedi" (2h 33m) was a better Movie than "Star Wars: The Empire strikes back" (2h 7m) just because the last Jedi was a longer Movie.

I know it is your opinion, but I need to dissagree here, because saying this had send so many wrong Messages to Game Devs and even created Websites, that try to determine the Value of a Game by a Euro/Hour ratio.

And those make it look like Destiny or Anthem are better Games, than lets say Silent Hill 2 back then.
Just because SH2 was a 60 Euro Game for 8 Hours, while Anthem is a 100 Euro Game for around 50 Hours...or even more, depending on your will to Grind the Game.
Or that Metal Gear Solid 5 a Game that was extremly streched to make it extra long is a better Game, than Metal Gear Solid 4, a Game that was from my View very well paced and was pretty close to the optimal lenght for their Story.

But you are neglecting the point, that eureka is exactly not for your friend but for the Players with too much time in the game. Eureka is completely optional content.
That said, if he wanted, 2-3 evenings a week would be enough to play Eureka; he would be max lvl if he had just done his challenge log once a week.

And here come the 2 big Problems:
Eureka sells itself as niche Content while at the same time locking the Relic behind it and getting handled by the Devs like the new Main Content.
4 Releases in 12 Months...that is a Niche as Omega or the second Dungeon with every second Patch from my View.

Mostly, because it is not fun. When you have maybe 4-6 Hours to play per Week, what would you prefer:
Doing a bit of Savage and Dungeons and enjoy the little time you have or go into Eureka and farm Trash Mobs for 2 Hours on 3 Evenings?
If he would like to do that, he could just play BDO, because the Combat of that Game is at least fun, when you farm Trash Mobs.

And doing the Relic for all 15 Classes is something for the Players who can spend +100 Hours per Month for the Game.
But Players with a Family Life Time Schedule often have even Problems finishing a single one...or reach the max Level of one of the Eureka instances without turning this thing into a thight scheduled Job before the masses have moved on.

This is a Game that is supposed to be fun, not a second Job to keep yourself busy.
