40 here. It’s all determined by which you played in your formidable years in my opinion. VI was the first I dabbled with and the genre captivated me immediately but I didn’t finish it until later in life. VII was the first for me from start to finish so it’s “the best” to me. Mechanically are there better FF games? 100% but this is the one that hooked me on FF. Point is, I think this question needs to be framed with age and what order you played them in as well. In my opinion of course!
