Any other feedback? Any other ideas of what to needs added to the OXP?
You're already off to a great start.. Just keep doing what you're doing.. adding more messages, and trying to think up as many potential situations/conditions as possible for passengers to remark about. And as some of the suggested remarks hint at, not all passengers are good-tempered. Some might be (vocally) anti-social. Maybe some are hungry, thirsty, horny.. whatever. Perhaps some like to party, or go bar-crawling.. Maybe some are sick of all the damn noise.. Maybe some complain about other passengers, if there are others aboard.. Perhaps some passengers don't get along very well with one another.. Perhaps some get along too
Oh yeah.. species-specific comments would be a good idea too. What special needs/interests/requirements might a cat have? A frog? A lobstoid? Would they be particularly interested if they arrive, in passing, at another planet with a species similar to their own? Or one very different? Certain species might not get along, and start fighting.. Maybe a Lobstoid keeps pinching a cat's tail.. he thinks it's amusing, she doesn't. Potential passenger interactions provides a lot of scope for ideas.
Another idea.. perhaps some things should be less
random.. maybe assign a personality and character type to a passenger when they board.. then keep all (or most) comments from that passenger in character.
Basically, exercise your imagination.. and keep soliciting for others to contribute phrases as well..
