People are too fixated on RE4 and even RE2, that they'll constantly feel the need to shit on the remake of RE3 and claim 5 and 6 are awful, even though these games play exactly the same. Really, I don't see any difference with 4 and 5 besides having Sheva as your sidekick. Even the remake of RE3 is just like RE2.
Every enemy from 4 returns in 5, more or less, with the gameplay being practically identical in my book. And Wesker is in 5 fighting Chris, so unlike 4, the events of 5 feel more conclusive. Wesker probably didn't even know about Leon before, but 5 feels like it properly picks up the arc after CV, with their fight by the submarine ending a little short. So why people act like 4 is a masterpiece and disregard its sequel, is strange to me.
It's also sad and lame how people hate CV and say it's actually meant to be a spin off. CV was in fact the real RE3. I guess if you want to label RE3 as being RE3, then CV is the real RE4 in a way. The actual RE4 is a new start for RE as a whole, so it barely feels correlated with the lore in any case. Yet CV feels like a sequel.
It's just that the RE fans are an odd crowd.
