How do I make a model resemble one with low poly count? I want to make a model look like a low poly count, very detail lacking figure such as like this:



Very much resembling mid to late nineties 3-D polygonal model formats that were run in games on consoles like PS1, N64.

If you could have a look and entail, what steps should I take to design a model similar to those?

Or like this, for a better overview:
It would seem you want to create low-poly art. The best way to do this is to actually model these objects to achieve this look and quality and then texture them.

No amount of modifiers or tricks will get the same unique look. Also using modifiers can make animating, texturing or rigging very difficult and also destroy your mesh topology something that is key in lowpoly style characters/objects.

The Decimate modifier might be of some help though, it can reduce mesh geometry but it is not very flexible and generally unpredictable in how it does this when used on complex objects.

Also as bummzack points out below, alot of the detail say you see on low-poly models is mostly from the texture(s).
