@Ganymede Well, the Dishonored series might technically be a shooter but you don't have to kill a single person if you don't want to. The option to choose between ghosting through the game, killing or not killing, is what makes it so fun. I strongly recommend this to anyone who hasn't played it.
AC is a little different. I hated the first one when I tried it but then Odyssey came out so I gave it a shot and really liked it. Knowing the others weren't like it, I tried Origins and then the others mostly because of the historical settings and a curiosity to see what they did with them.
I still wouldn't say I'm a fan of shooters as I really don't like the Bioshock games or some others I tried.
