Also totally agree with Obsidian Ant.
Flying ships, exploring systems, landing on planets and startports, docking as stations and outposts is great. The game's setting, the galaxy, the planets, the ships, is an absolute masterpiece. FD went out of their way to recreate the most plausible reconstitution of the galaxy ever. Went out of their way to create incredible planets, simulated dwon from their tectonic plates, to make them as plausible and believable as possible. Celestial objects are done in an magnificent manner, some are absent, many are present and realistic(ish).
The "gameplay content" on the other hand, is not so shiny. Far from it.
A few days ago I wrote on some other thread that FD created the most impressive and glorious game world that has ever existed, but keep failing to create a compelling game on top of it. And that is because FD keeps adding self-contained, disconnected, isolated minigames after minigames, without any kind of cross interaction whatsoever. And that is what leads do the overall feeling of ED being a half-baked game, the famous "mile wide inch deep".
With Horizons we basically got new doses of the same existing 2 plates: Incredible, realistic(ish), magnificent reconstitutions of planets to add to an already absolutely incredible game setting. And another pack of self-contained, disconnected, isolated, minigames. The new activities do not connect with existing ones, nor do they expand them.
ED's gameplay part is too much like a theme park, or an arcade salon, with its individual, standalone arcade machines where we could put a bunch of coins and play that particular machine for a while. And that is a shame. Feels like the huge potential of the game setting goes somewhat to waste.
