I have heard this game (favouribly) being compared broadly as a kind of 'space solitaire' game. But it doesn't look or even at first blush play like solitaire, so I want to explain why the analogy works for me:
In solitaire, you have the same 52 cards, arranged in such a way that their order is different, so sometimes you might get snuffed out early by an unlucky deal, and sometimes you might fly through for victory - you don't really mind which, because games don't take long so the stakes never feel so high that you'll never play it again.
Weird Worlds shares some of this in common. The star system is filled with mostly the same items and hazards, but the order you encounter them switches out, so in one play through you might have exactly the item you need to best deal with an encounter, and another time you might not.
This means that a lot of it is luck based, but half the fun is replaying the game and seeing where luck will take your exploration of the galaxy this time.
That's not to say it's all luck - fitting out your ships with the best gear takes a bit of decision making, and it's possible to learn the function of special objects to understand whether they're worthless and tradable, or could come in handy. Plus the real time combat segments are basic, but reward people who avoid combat before becoming sufficiently tooled up.
Occasionally, too, the game likes to switch things up by layering a 'meta' plot, usually difficult to resolve, above the usual exploration. Some sort of crisis which the player must solve in order to score a 'win.' These are rare, but always welcome.
Like Solitaire, this is an ideal game to kill a short space of time with, but better than solitaire, it rewards repeat play with just a modicum of depth to be discovered beneath the surface.
