Oooh. Any easy one. Stellaris is an absolutely terrible entry in the 4X genre.
Stellaris not only lacks micro-management, it lacks any kind of management. You don’t really make much in the way of decisions, period.
The early game is all about sending your exploration vessels around, moving from planet to planet, scanning them as you go. This is far less interesting than, say, a Civ-like game, since functionally almost every planet or moon you scan is exactly like every other planet or moon you scan. Almost none of them are habitable, and most given a generic bonus to one of the resources, so they’re pretty interchangeable.
The habitable planets you find are pretty interchangeable, too. Mostly what matters are the number of squares on the planet, and the habitability rating, which is a number from 0% to 100%.
So, you plant colonies on the few planets where you can manage it, up to your empire limit, and you plant mining / research stations everywhere else, up to your upkeep limit. Then you stop.
It’s extremely basic and rudimentary compared to almost any other entry in the genre.
When you meet other races, they’re either basically friendly, or they’re not. If they’re inclined to be friendly, you can grind away until they like you and sign a non-aggression pack. If they’re hostile, absolutely nothing you can do will change that, since they’ll reject any action that will improve relations, and they’ll get angrier and angrier at you until you’re pretty sure they’re going to declare war.
You could declare war on them pre-emptively, but why? You’re probably at your empire limit by this time, and can’t expand any further. So a whole lot of nothing follows.
That’s as far as I got after 12 hours into my first game, and I said “screw this” and uninstalled it. Maybe there’s more to the game locked beyond another 10 hours so of play, but if I can play a strategy game for 12 hours without really doing anything remotely interesting, I don’t see the point in continuing.
