This is technically my first ever post on these forums so I beg you to be kind! I am considering attempting to write a few stories set in my own universe in which great factions wage territorial war throughout the cosmos. That sentence however cover a lot of concepts already done in sci-fi, I shant mention any for fear of doubting myself further. I was simply wondering if you think it's done to death? OR perhaps that you can do any topic any amount of times? Really doubting myself!
