I can't agree with that. RE4 in my opinion was just as bad. I can't think of a single puzzle that requires me to really use my brain.
Use your brain? That's what they all did. If you mean, stump you really bad, maybe not so much. If that's what makes a game good, getting you stuck and really have to think in order to figure out a puzzle...well if it's something that really makes you think, okay, but if it's just really stupid, and obscure, and not logical, RE3 is probably the worst perpetrator.
Anyway, RE4, the one where you get the catseye, that one required you to think. The one with the lights was a visual thing, not too hard, not too easy.
The one with Ashley, where it's dark, foggy, and you can't defend yourself against the armour ganado things. You only have a flashlight. Anyway, there was that puzzle with the squares...it's an actual puzzle, not just an RE puzzle...can't recall the name though.
It also had the other kinds of 'puzzles'. You know, the collect a couple of items, combine, use in order to open a door.
The hedgemaze was great.
There are some more, if you require me to point them out. I'm just trying to point out, that there are some great things, being boxed together with RE5's overall horrible puzzles. That's not fair, certainly not agreeable.
I mean, it's not even an opinion thing, RE4 had puzzles. Some made you think. RE5....well it had a couple, and probably only one that was good, and made you think a bit. Nothing that would stump, but let's also forget that having a forced partner probably affected that too.
