It took me two tears to develop the story to Shadosassins. I didn't like the story I started off with and it took me quite a few re-writes to get the story to where I wanted it and that included its environment. I left small holes in my story that I can change on the fly if need be just so things didn't seemed overly structured when I actually started making pages. I my story has a defined beginning, middle, and end, but I left little areas of how I get to these points changable.
bout 40 years in the making 
their are elements of Tales From Swipe City that are reflections from my life. one of the characters in it is based on my mother (nobody tell her that !) another character is based on a very horrid teacher I had. and one or two other things that happen as the story moves on are based on events in my life ( just hyped up a little) .
one tip I will give people is i sometimes plot events backwards. that way you can move backwards along the time line until you work out the best place to link it to a current running plot line.
Starting from the very first scribbles of characters in the notes of one of my college classes to "get the idea out of my system" so I could work on Serious Projects (hahaha) to me posting the first page online was somewhere around 4 and half -- 5 years. At first that was just me pondering ideas, sketching character thoughts, considering the world. Then, when I finally realised this wasn't some dumb idea I was gonna drop after a month, I started trying to make a rough outline of the plot, figuring out how different events would lead to each other.
Runewriters started out with 3 main characters and a couple of side character concepts. I realised what the story was about after I finally conceptualised one of the major villains. It now has 3 main characters, 3 other major characters, 3-5 main villains depending on how you count, and a couple of side characters. I, uh, have a tendency towards ensemble casts,,,
When I first started posting Runewriters online, I had a half-finished script of Chapter One, a rough outline of events for Chapter Two, and things like "this is where they meet character A" "this is the one where so-and-so fights such-and-such" for the rest of the chapters. Somewhere in the middle of drawing Chapter Two, I completely rewrote the order of events for Chapters 6-9.
Currently I've just finished Chapter Three, I have a full (rough draft) script for Chapter Four, I'm working on a more detailed outline of events for Chapter Five, and I have rough "here are the things that need to happen in this chapter" notes for everything else that I think about constantly in my free time. I like thinking ahead but not laying everything in stone just yet, to give myself some room to have new ideas!
And it takes me about 10-12 hours to finish a page because I'm a huge slowbie.

world at strife started out as a little idea my friend and i had back when we played this social media game called "TinierMe". it was basically a shittier version of gaia online but we had fun with it all the same. i met this friend through TinierMe and we joined a group to discuss games and stuff. at that point i was in middle school drawing and i figured "hey, i can make a comic about our group talks and stuff" and i started doodling cover pages and junk. as I grew up i started to think my old work looked like crap and once TinierMe started to dissolve my friend suggested i make a comic about our OCs from TinierMe, which would later become the main characters in World at Strife.
world at strife was an idea we pitched ideas for for years. when i came back home from school i would talk to my friend over skype and we'd come up with goofy plots and characters to add to the story. after a while i actually tried making other comics as prototypes to see if i could do it. all of them failed, and i stopped working on comics for about a year. in 2014 i finally got the resolve to do WaS, which would eventually be tempered into what I have today.
i planned out the beginning and the end, i just wing the middle.
I have a tendency to come up with huge amounts of different characters, combining some of them in one story idea and trying stuff out by just sketching character interactions and such and working from the perspective of the characters and their chemistry. Some work, some don't and the ones I've grown most fond of tend to stay with me.
I've really been into comics for as long as I can remember so working on the story by simply writing it down isn't really natural for me so I mostly come up with really basic plot points and only write dialogue for character interactions down, the environment, body language and such feels really difficult to describe in words but come out more naturally in drawings. I've tried to get to the habit of actually story boarding my pages beforehand these days because that way I can actually show them to people for critique to make sure things come out as I want them to and the flow doesn't confuse the reader.
I used to brainstorm stories a lot with an old friend of mine but since ours interests story-wise have floated in different directions I'm mostly just work out the stories by myself maybe getting a second opinion here and there from someone else..
It took us a single day to come up with Tales from the Well XD we had to pitch the story for class the very next day with plot, character designs, and a summary of the first episode.
I agree with most of what was mentioned here for plot development. Rough plot idea with major story points planned out. Enough to have a plan and enough to be flexible =) also keeps you interested in the long run!
Hmm... that's actually pretty difficult question, since I re-vamped my comics there were 2 ways I did the plot thingy. First one I was bored and... and needed a man (XD) So I started to write short story. It was basically a soft erotic. I didn't thought much on the plot, I would make it a one-shot. Later my friend was like,: develop it more! And I was like: OKAY :v and I started to write more. I was just going with the flow, but to be honest, it created a huge plot holes when I tried to add more and more things, so I would recommend not starting your story not knowing the ending.
When I re-vamped my story for 2 months I was writing the script, AFTER I knew where the story is going, so my process looks like that: IDEA ON MY HEAD > WRITING STUFF ON TINY SHEETS > START TO WRITE THE WHOLE.
Before I started to draw (since I don't really do storyboards) I had 8 chapters done (about 15 pages). The script isn't finished, but I have already planned the main events in the story, so the smaller ones to connect the dots are less difficult. And I'm sticking with it, with only small changes in the dialogue.
How long does it take me to finish one episode? Let's see... 30 or 40 pages... it will be about a month or a bit longer. Sometimes I re-draw pages, that didn't turn out how I wanted.
Okaythatsallbyeeeeee.
