a matter of having the time to sit down
I can relate to this! We have years of content built up - then I come to steemit and half of what I write are new poems and contest entries!
In terms of length - I would still say it is long. Not too long to read, but I scanned it, got excited, left my upvote and came back to this post at the end of the day. Though I am no expert on how long things should be, I like books!
Oh! Yes I remember you mentioning the game but not that it was your game - very cool! I am a big fan of world building - and world builders! You have at least one fan eager to read a page per week :)
I think what I shall do is post a few of them at around this length (assuming they have a decent point to be split this way) and then re-evaluate. With any luck I'll push one out, edit the next few, and build up a back log of posts so I can have steadier content.
Hah, that's what I've been doing lately. I give something a quick scan for quality, upvote it, and then I can fish it out of my upvote history to come back and read it.
