I dont know who borrowed from whome...but RE2 and RE7 are interestingly similar ..in a very good way
this game is giving me so many feeeels
Both are Capcom games ya know .. makes sense there would be some shared commonalities
Yes I know what you mean, RE2 is using some HUD and design elements from RE7 which is A-OK for how quick the turnaround for this game was.
How different are the 2 campaigns (Leon/Claire) from one another ?
They both run into unique NPC's, most of the areas they both visit are the same but there are around 20% unique areas in their campaigns which only one character visits.
You need to beat one full run (i-e Claire 1st run, Leon 2nd run .. or Leon 1st run, Claire 2nd run) to get the complete story. Don't worry about the 1st/2nd run part, once you play the game you'll know what that means.
Does the game still has Leon A/ Claire B, Claire A/Leon B campaigns?
Yes
