I liked the remakes of 2 and 3, and 4.
5 and 6 were fun to play co-op. I generally prefer third person games, which is why I haven’t played 7.
5 was over the top, and I like how in 6, there was a marked difference between playing as Ada, Leon vs the more action heavy Chris playthrough.
They could do another game like 6 but go harder with that concept of picking your play style.
Hmm, it sounds like you need to use something like Calibre to export all your books to a single standard format.
