Oh...that...yeah...I admit that even I sometimes feel too lazy to stop playing and do something productive, though in my case the games involved were Dark Souls and Mass Effect...that spreadsheet on the other hand is quite the problem, cant run away from it.

Self Incert! Thats the word I was looking for! Those can and will cause a major problem in your story, I cant express how frustrating it is when they are shipped with a major character from the show, or somehow are alicorns, thats just asking for flame war, and we know not to play with fire.
Brief mentions and shout-outs are fine in my book, no harm can come from that.

I also think another cardinal rule for writing OC's that are going to be even remotely prominent in your story, is no self inserts! Ever! If it's a short or passing mentioning of yourself, such as what V-Pony did in his story Blue Angel (He used a fan's OC briefly as a shop owner, and then the OC was never mentioned again), then I'm cool with that. It's kinda like a shout-out. But when you do a self insert where you're the main protagonist, or even a recurring minor role in the story, you're bound to run into problems...

Season 2 you say? Dear Luna...for how long have you been writing it?! It should have been all done by now, a whole triology! What kept you from writing for so long?
Thats how its done! OC's got a bad reputation due to bad writing and...well...bad writers, yeap, those are two tottaly different reasons, there are more, sure, but even I got an OC, so I cant get mad at people simply for having one in the story, just gotta have some boundaries, best thing is, like you said, making them not a huge deal in the plot.

1144040 Eh personally even if my story flopped I'd still write the sequel just for the sake of writing it. Though I came up with the idea for this story and the sequel way back during season 2, but all the new episodes in season 4 have given me all kinds of new ideas and possibilities for the sequel.
But yeah I hate it when authors do that with OC's! I've always tried really hard to make sure I stay as far away from that as possible. This is a Scootaloo story, and it's gong to be about Scootaloo. Every other character is replaceable without the story losing it's original plot, and I'm going to keep it that way.

Already planning for the future eh? Nice to see that, means you are confident with your story.
About the OC's, most of the problems I have with them only happens when the writter inserts his own into the fray as some sort of main character, close or related to the Mane 6, super powerful and all that, it ruins the story and makes no sense! Only to make him look important. If they are written well or are just there as background characters its fine by me.
