ahhhh, this one is a little hard, to be honest.
for long stories- it’s more the concept/theme of the story. Like the aidlock one- wanted to play with opposite factions, a character that is so chirpy and happy verses one that was doom and gloom…. A once dreaded companion turned into a desirable one. So, what gets me the most excited for longer stories is the theme of it. Yes, the characters def help- but truthfully, long stories are usually of my picking.
the all time easier standard would be Ratchet- just because I have done so much with him and you can really play with themes with him- he could be grumpy and not happy with wg, or cuddly and happy.
best dynamic: an overinthused feeder and a very willing feedee. Obviously Aid fits the first.
worst dynamic- as in hardest to write; forced feeding. It just feels very hard for me (but gives me something to work on)
for drabbles: fav feedee is Blast Off, followed by ratchet and first aid. Brawl is a good one too- but haven’t written much with him.
for vore: fav is sunder- but the only other contender was shockwave
worst ones: honestly, it would come down to characters I don’t really write much about/know much about.
of course I done some other ones, but those are the ones that stand out the most for me.
what about you, fellow readers? What are some of your favs to write (or read about if you don’t read)
