Almost nothing labelled as "low-poly" is actually low-poly. It's really clear that most modellers have no understand or simply do not care how wasteful their geometry is. They just assume everyone is prerendering, instead of actually trying to fit it into a real-time game engine. Half the time "low-poly" just means xbox360-era models, then the rest it's just aesthetically low-poly but not technically.

Anyways this really blocky looking "low-poly" model has 11,518 polygons vs 3423 for Half-Life loader.
