Yeah I do enjoy it!
Each version is all different. I've actually socketed the ideas away to use as a Multiverse. The alternate versions of the main character Rip, I refer to as DoppelRips, and I've given them different personalities and abilities, so each one feels unique.
I still give myself room to add improvisation if I feel something isn't working in the canon. I like working with an open mind and a fluid universe.
Most of the older versions were never written down, and just lived as sketches, doodles, and daydreams for the last decade. So when I sat down to actually focus on it, it was odd at first.
A lot of people say not to do your 'magnum opus' first, but that's what I wanted to do. I don't think it's the only comic I'll ever write but for now, this is the one that I want to do. I lived with these characters in my head for too long not to.
