Self Destruct:
1. Sounds cool.
2. Pretty HRP. Defending SD to get rid of xeno scumms - heroic.
3. Very original and unique idea.
4. Brings joy.
5. Creates a lot of memorable moments. (Nostalgia...)
Lifeboats:
1. Sounds lame.
2. LRP. Standing near lifeboats to escape - autistic and cowardly.
3. Turns game into cookie cutter shooter. (Alien crashed ship -> now you escape)
4. Stupid delay which makes no sense.
5. Creates a lot of admin meme moments.
"But SD had bad map design?" - Well then remake design duuuh, not remove it entirely .
