I enjoyed the original trilogy massively, particularly 1 and 3. I will give it to 3 due to being technically superior. One of the few games with perfect balance, I feel.
Haven't played 2018 due to knowing that I wouldn't like it. Everything I have seen from the game has convinced me. I will play it if I get it for free though.
I hope Ragnarok takes some major risks, but it looks more of the same.
