So I was heading over to a friend's house for a beer last night and I packed the Deathwatch core book in my bag to take to show him but my cat started making a lot of noise. Turns out she wanted me to leave the book so she could get her character together for the upcoming campaign to run parallel with the RT and DH campaigns in progress.
Now the cat doesn't have a problem playing outside of species and has been really enjoying her Explorator in our RT campaign, but would prefer if her Deathwatch space marine character were a cat.
So what are the options for Feline Space Marines? Could the lost primarchs have been a dog and a cat respectively? Would a space wolf rivalry ruin the party balance?
