I do like writing with other people, in general. It just depends. If everyone writing is equally motivated and on the same page with where the story is going, then it usually works out great! I find that I am more creative when I'm writing with someone else, maybe because we kinda bounce off each other, and we both end up writing better than usual. Plus, it's fun to share that experience with someone else!
I've done collaborations with one other person, two other people, or big groups (say, 7-9 writers). Oddly enough, I've had the most success with the big groups! Duos only work if both people are motivated; once one person slacks off, the whole thing can easily fall apart. Also, it's hard when you don't see eye to eye on things because there's only two of you to talk things over, and if you each want something a different way and can't find a way to compromise, that's a problem. I've never had success with groups of three - it's too easy for one person to feel ganged up on by the other two when they get overruled on something.
My first BIG collaboration that wasn't just a round robin was Code Blue, and it was my idea to try it with a "writing team," the way TV shows are written, after writing it in twos and threes didn't work - it was basically a last ditch effort on my part to keep the story going. I just threw it out there that I was looking for people to help me write the story, and I basically took on everyone who volunteered and could string a coherent sentence together, and I ended up with a group of 7 people, some of which I didn't even really know. I thought it would be a disaster LOL, but it actually worked out really well! We plan the story through group chats, and when we all get together and discuss, we come up with the best ideas! The only problem is getting everyone to get their parts written in a reasonable amount of time... we've been bad about that lately. We need to be stricter about setting and enforcing deadlines for ourselves, or we'll never get episodes done.
00Carter has worked out much the same way, only even better! That group is amazing!! We can take the most random, stupid idea and turn it into something coherent and BRILLIANT! I feel I can say this without sounding arrogant, because only a small fraction of the story is actually something I've written, but 00Carter is awesome so far! Everyone should check it out!
