I have mixed feelings as a whole because tech webs are not new, didn't Endless Legend have that? Cross promotional material isn't new either in fact, didn't Endless Legend & Dungeon of the Endless have that as well?
If you're talking about the bonuses for Endless Legend, all you get from owning Dungeon of the Endless is basically a new "space skin" for one of the factions. These are the Vaulters from the base game and these are the Mezari you get for owning Dungeon of the Endless. As you can see, they've got the exact same stats, they just have different-looking units and dialog during diplomacy. Which is more than can be said for the factions in Beyond Earth.
On the other hand, owning Endless Legend does give you a ship on Dungeon of the Endless that you couldn't get otherwise, but the devs have already announced that they're trying to find the best way to make it available to those who don't have any interest in Endless Legend. And again, that's more than you can say about 2K or Firaxis. You want that fancy new Ultrasonic Emitter or the Colonists in BE, then you'd better have Starships, and if you want to have stuff in Starships that isn't even content but just changing some numbers in the coding of the game (like being able to use two affinities at the same time or planets that get bonus resources), then you'd better have Beyond Earth because you're not getting those any other way.
Like all companies Firaxis has to keep up with the times or risk going under but I want to feel like I am buying Firaxis games not angry birds clone #619. If I want Endless Legend, I'll go buy Endless Legend with all the "cross connectivity" games as well as DLC and a forum exclusive avatar if I pay double and get the 'founders pack'! Sheeh! At least Firaxis haven't gone that far.
No, they've just sold you what's basically a reskin of Civilization V with less content and still had the gall to charge you $50 for the privilege. Meanwhile, the Endless Legend devs made a much better game, for which they're charging you less money and is already on its THIRD completely FREE mini-expansion that includes new minor factions, new quests, new victory conditions, fixes, balance changes, etc. etc.
And I'm sorry if I'm coming of as a bit aggressive, it's not like I'm angry at you or anyone. I'm just bitter at how Firaxis let themselves be schooled at their own game by a group of much less experienced devs just because they have one thing that Firaxis doesn't have anymore: a true love for the games they're making.
