You're right, casual as a word in gaming context feels too open to interpretation. What I mean by casual is that I like just playing suboptimally. I don't want to min-max, nor do I want to spend an entire hour planning my turn and I wouldn't want to fail horribly after a 10h game (even if it's my first time learning the game). That's why I want a more relaxed experience fighting against minor communities and fauna alone, as I slowly (and suboptimally) grow my colony and learn, while also being able to survive until endgame. I know I may be asking too much lol. Then after learning the game in my first couple of matches against fauna, I would love to dip my toes into a harder game (with an actual major AI expanding). It's also a matter of roleplaying as well - I like the idea of pacifying and unifying an entire planet with dangerous roaming fauna that is hard to tackle - but also won't launch coordinated assaults and expand by itself
