Coincidental timing seeing this thread pop back up, as I'm just playing through RE8 having played RE7.
RE7 was another mixed bag, loved the family and shock moments, gameplay was pretty lame (again) and structure was a bit dull. Was OK for a while 6.5/10
RE8 is the best in the series I've played so far, it certainly has the best gameplay. Some of the environments are awesome, the variety is great and the characters are cool too. There's also some really intense moments which, if more regular and less padded out by bullshit ammo/item hunting, had potential to make it amazing. But it's also paced really erratically and the boss fights are really basic too. Solid 8/10 game though, definitely worth playing.
