I realized that I really like Canon Welding
trope and I'm thinking of using it in my few projects. Main idea is to reveal, in some of the later works, that they all take place in the same Universe but at the span of hundreds of years, if not more, so they don't really interfeere with each other, sorta like Turn A Gundam
did towards other Gundams.
I wanted to ask, what should I take advantage of and what are pitfalls I should try to avoid?
