I think these conversations should be more varied as to giving the player to choose his response on several occassions. For example, You could try to comfort your Rockman when he talks about his family, or tell him to forget it. These choices would only be for flavor and would rarely have event outcomes. Another idea is to implement in specifically to humans, as to make them more interesting to talk to (even though their race description clearly says otherwise) Like, you could come upon a rare event where your crewman has some leisure time and you are free to ask him about certain questions, similiar to Mass Effect. Or, you could disturb your crewmembers in your quarters and see whether or not they would mind your presence (I'd laugh out loud if you could have intimacy with your human crewmember, resulting in you to spend quite some time that the rebel fleet starts to catch up on you
) Still, this should be possible on a few occassions. I'd very much like more activity and content while socializing with your crew. An example I've come up with, but could also go out of the boundaries of FTL's hardcoding: your mantis crew would ask to fight with some of your crew to improve it's skills. You could choose to agree or disagree and if agreed, Your Mantis would be converted to an enemy , allowing you to fight it in game. If killed, the mantis would compliment you in the way you've handled the situation and patch up in the medbay. Then, the mantis would return to your crew with the same name.
A lot of times, The anti-system augments really disturb you and frustrate you in combat. I suggest that there should be a way to counter this, apart from Lv3 oxygen agains't irradiators. For example, An automated re-loader could be used as a blue text event response to prevent your weapons from being hacked, A drone reactor booster/It's new name could be used to prevent your drone bay from being hacked and the Reverse Ion Field could be, well, you guessed it, to deflect Ion Fields disabling a bar of your shield.
I'd also like it if there would be a CE-specific protection augment, which I'd mainly refer as to, Fireproof System Casing. As obvious, it would have a high chance at resisting damage done by fires and Solar Flares, and if possible, increase the amount of time a bar of your system would burn.
Oh and, this has been suggested several times before: Will Rock ships (Atleast, those with it's respected augment) Be able to ram ships during combat to disable a random or specific system?
