: Aside from the hiccups (and I don't know how that got past testing), what's
: wrong with it? Also it was adapted from the PC version's code, and I'm
: pretty sure the PC version didn't have any graphical glitches the original
: didn't.

Haven't we had this discussion before?

Here's a summary:

Material shading in general didn't port very well from the original game, transparencies are incorrect, lots of parts of the fog system don't work, some assetts were replaced, dynamic lights are calibrated really oddly (in CEA, at the very least), and some stuff flat-out doesn't render at all.

Here's the long version.

: There were
: games for the original PlayStation that had more detail in some areas than
: the first Halo had in most Forerunner structures.

That's a pretty big stretch; it's only especially true with pre-rendered stuff in PS1 games. The PS1's 3d functionality is really primitive.

: I don't know what you mean.

When things are visually busy, it can blunt the aesthetic effect of how the carefully-placed colours and geometry slice through the sky. It becomes much harder to produce a good, cohesive layout.
