Well, I'm not so sure.
I'm not a hardcore gamer, and I've never even beat AI War on a difficulty higher than 6. I have the grand strategic instincts of a weasel. I send my big ball o' dudes around, and look for places with neat things to find. I play with all ship types enabled, even though I have no idea how to effectively use over half of them. I love finding an Advanced Research Station and seeing what weird ships I get. I love the wormholes and the little mini-quests within them, and I love my flagship that can level up and transform. I love the lore and world-building, and how the game manages to do so much with so little. My typical endgame is building up a fleet of 2000 or so ships, along with my awesome flagship, and just dramatically hammering at the AI homeworld. I always imagine myself on the bridge of a command ship, steadily battering down the shields of the enemy fortress as each of its cannon blasts wipes out dozens of my ships. When I win I always feel like the reincarnation of Napoleon and Alexander the Great combined. And I can do this without having to feel like an idiot by placing the difficulty on level 1, because the game is easy to pick up and has a very clear relationship between action and result. I.E. You died because you didn't put enough turrets around your base. You died because you provoked the AI when you shouldn't have. You died because you triggered the Spire Quest and you weren't ready for it. Each failure gives you immediate information that you can use in your next game, and as long you avoid a bare minimum of stupidity, you can have a good time and not get immediately wiped.
Recent Arcen games seem to be trending towards a different direction.. I beta test'd Skyward Collapse, and I gamely tried to play it, but games mostly ended with somebody (Usually the Norse, I think?) getting blown up and me not being entirely sure where I screwed up. I had more or less the same experience with Bionic Dues: I'll do just fine on the first level, and then on the second I'll get blown up by some enemy with rockets with no idea of what I should be doing that I'm not. I've more or less put the both of them away, and don't know if I'll be going back to them any time soon. I'm sure that with repeated playthroughs I could go back and figure it out, but it would be a lot of blind fumbling before I started having fun. Both of these games seemed to have the same "Play it and fail, play it and fail, and maybe by the 15th game you'll stop failing" attitude towards difficulty. It feels like playing Go against a veteran player: there's a lot of depth, but none of it is clear to you at the start, and you're going to lose over and over until that depth becomes apparent to you.
I've got similar hopes for Last Federation. It sounds like the world is fun and well fleshed-out, and I love the concept of running around in my small, elite ship and doing cool things as part of a master plan. I've read in the promotional materials that you get to put rockets on a moon and slam it into a planet. I'm not sure why you would want to do this, but I can't wait to try it. I've held off on signing up for the alpha, even though I did for two of Arcen's last three games, because I'm worried about the difficulty and the level of time and frustration needed to understand the game properly.
Now, some people love this kinda thing. Witness the popularity of Dark Souls, or I wanna by the Guy, or any of those sorts of ultra-difficult games. And if that's the target market that Arcen is aiming for, then more power to them. They're certainly under no obligation to make games specifically tailored to me. But a forum like this is naturally going to attract a more hardcore crowd, so I thought I would throw my opinion in as it may be underrepresented here: I don't want a high base difficulty. I want to have fun with it out of the box, and I don't want to have to turn it down to "So easy a goat can beat it" to do so.
