Their storylines feel suspiciously similar, IMO.
I've seen brief clips of them and they turn me off. Compared to every other re entry, any silent hill game by comparison is much more scary and a lot more disturbing while re games by comparison are a lot more action oriented filled with a lot of drama. This of course applies from re1 to re6 cause starting with re7, they imitate tropes from western horror media much more and they dont feel like they fit to the series when compared to past.You should try 2 and 3.
Even the original is great, but the old graphics may put you off.
Would you say that re4 is inspired by silent hill 2 plotwise? Apparently both games dont have much to do with the past storyline and this is another aspect that carries on to re7 and revillage? I still dont know about the plot of those games that much and ı only remember the protagonist of the 3rd game who reminds me of sherry in re6 but other than that, not much really. I think this is another reason why re engine direction is even more meant to be a direct follow up to re4 storywise, they even play more similar to re4 than other games in the series really.Personally, I would love to see The Evil Within revived, as it's like SH and RE combined.
