High resolution pixel art is usually found in backgrounds of 2D games and is also used for characters in some 2D fighting games. For these you usually want dedicated pixel art software or at least few helpful plug-ins for GIMP, but even Microsoft Paint can work here. These don't really like rotations that are not multiple of 90 degrees or on any other plane than the screen plane. These assets only like scaling upward in even numbers (2x, 3x, 4x etc.) and you should use the scale consistently. In these cases each individual point of colour is important and you might want to also consider things like limiting palette to fixed colours and how many screen pixels each of your asset pixel is going to take, as singular pixels in modern screen are quite small.

Pixelated sprites are what you see for example old rpg and platforming games, modern indie games imitating them and "HD-2D" games like Octopath Traveller.


It is quite tech dependent, basically there are 3 options for 2D art assets: pixelated sprites, high resolution sprites and vector graphics.
