I couldn't finish the article. I tended to aree with the guy, but he lost me at Skyrim. It was more shallow than Morrowind, but it also made a lot of things better. Having to put on my uniform to get Legion quests sounds like great roleplay on paper, but it's just a hassle in practice, and while character creation in Skyrim is much simpler, there are more and better customization options through the perk trees.
Here's the thing about appealing to a wider audience: Turn based strategy games are inherently a niche genre. You can make them more accessible by improving the UI and in some cases removing mechanics that make them more complicated but don't add real depth, but there's a limit. It doesn't just apply to TBS, but pretty much every genre that isn't explicitly marketed to stereotypical teenagers and frat boys. There are games that managed to pull this off: Skyrim and Mass Effect 2 are good examples, and possibly Enemy Unknow, which I really enjoyed, but can't really compare to the original X-Com which I never played.
Developers fail when they don't understand why a genre is popular with its fans and cut off integral parts when they "trim the fat" or introduce elements of more popular genres, or just plain mess up.
That applies to many EA games, but other publishers are just as guilty. Dead Space and Resident Evil wre transformed from survival horror into third person shooters, Sim City was reduced in scope and downgraded to make it less complicated for the Call of Duty crowd and less interesting for city builder fans (and we don't even need to go into the always on debacle. Two of those series are dead now, Maxis lies in ruins, and Visceral Games will soon follow, and Colossal Order has made a proper Sim City which has already sold half a million copies within a weak. Of course half a million copies is not much for a big publishers because it bare makes up for the ridiculous marketing budget, let alone the overblown development cost, but that's another issue. What does that have to do Firaxis ? I'm not entirely sure, I've gone a bit off track now.
Ah, yes. The developers of Beyond Earth don't understand the audience. Neither did John Shafer with Civilization 5. Both games are more shallow than Civ 4 vanilla. Both have taken out important parts of their direct predecessor, seemingly without much thought behind it. Civ V got rid of religions, growing cottages, health and city flipping, and changed the maintenance system to make larger emires a thing of the past. Beyond Earth made diplomacy even worse than Civ V and removed any reason to aspire for friendly relations, and got rid of Great People, thus making wonders far less appealing and specialists practically useless.
I don't know if I should have any confidence in BE. I used to say that if Civ V could be salvaged, so can BE, but the recent patch was a huge disappointment and many of the changes seem to suggest that they don't understand their own game. They don't understand what works for us, they don't understand what we like or dislike. The big issues were ignored (diplomacy, specialists) or exacerbated (wonders), and they didn't even fix the two borderline gamebreaking bugs they introduced in the first patch (eternal war and no quests past turn 100).
