Welcome to Game Ideas Wiki

You don't have to start over, you just have to do the history edit comparisons, and do a lot of copy pasting and some editing to remove a few artifacts that will be popping up. I can see if I can find one of your subsections in their latest appearance before being removed and see if I can restore it for you or something, let you see how it turns out. I'd be for bringing back the full article but I am seriously mentally drained and we have a windstorm so I am more likely going to fall asleep or lose my Internet connection for the night at some point here, haha.

However yes, try to always keep back ups, or do what I did and make your own wiki specifically for your own stuff so you can stay in full control of it. Heck, you can even store it at my wiki ( Creativity Wiki ) and be safe in knowing I won't edit it unless you want me to for grammatical fixes or anything.
