Seriously. The PSP was a portable PS2, while the PS2 was still on top of the world. The DS was a gimmicky toy that sold better because it was priced and designed for play.
One aspect of that which seems obscure: the original DS used scanline graphics… for 3D. It could draw exactly 1000 triangles, row by row, at 60 Hz. This made low-poly games dead easy to optimize, and high-poly games an absolute nightmare. This also only worked on one screen at a time, which is why the second screen was always a map or a menu or something. The easy way to do 3D on both screens was to alternate, but that drops the framerate to 30 Hz.
This era ended for me not when technology shifted, but when I moved from a northern climate to the subtropics.
The shit I’d have on me when I wore a jacket everywhere was downright cartoonish.
