This is probably only true if you're thinking of the complexity in terms of board-game style complexity, with characters and items and abilities that you can enumerate in a list. That's the type of thing that digital computers are pretty good at doing and analog systems aren't, so in our digitally-soaked culture we tend to appreciate it more and associate it with being "more complex". But it also hit a saturation point in the 90's, right around the time SMW came out in fact - there are plenty of early 90's PC wargames and RPGs that are just baffling to play because they model the playspace in a way that makes for spreadsheet UI.

Detailed physics and AI, on the other hand, is a thing that is largely beyond the ability of the SNES platform, and that's something that started to pick up along with 3D gaming. We don't greatly appreciate these things in video games because we can pretty easily play with blocks and balls or find live opponents in the real world, but it's a realm that still has a lot of untapped potential.

Mario World does have a 2D physics engine with tile-based collision detection that works on 255 objects iirc.

The physics it implements is cartoony in that max velocity is capped such that acceleration is limited, but it's an implementation of verlet integration, more or less.

You can see the devs playing with it in a few levels. For example there's that long vertical fall with multiple objects falling along with you that leads into the 8th world.

Or a few levels where an enemy causes chaos with a turtle shell.

Errr... yes? Obviously, nobody is claiming that the SNES was capable of "detailed physics and AI."

My first thought was that perhaps you were replying to the wrong post, but there aren't many replies. You certainly don't seem to be replying to what I wrote, so I'm baffled.

Let's go back to what I said. I said it took a while for 3D games to catch up to latter-day 2D titles in terms of "range of interactions."

In SMW, Mario can...

- Walk - Run - Jump - Spin - Swim - Hold an item - Throw an item - Throw a fireball (as Fire Mario) - Drop a reserve item - Run jump - Super jump (with Yoshi) - Fly (as Cape Mario) - Crouch - Climb - Smash into the ground - Swallow an item (with Yoshi) - Spit out an item (with Yoshi, will have different effects depending on what was eaten) - Transition between different states (small, big, Fire, Caped, each with or w/o Yoshi)

Mario has dozens of abilities in SMW depending on which powerup is active and which (if any) of the Yoshis he's riding, as well as depending upon what Yoshi has eaten. There are dozens of objects with which they can interact, and many of those objects can also interact with each other. There is a physics engine, albeit a simplified 2D one, with gravity and momentum.

Contrast this with, say, Quake. You are of course inhabiting a fully 3D world, but there are a smaller range of interactions possible.

As I said, "a lot of" 3D games from the following decade (SMW came out in 1990) didn't have as rich of a range of interactions available. They were 3D, but there was generally less to do.

I can think of some exceptions, mainly from the latter half of the 1990s, but as I said, it generally took a while for 3D games to catch up.
