Adult Empire is less a studio than an entire ocean of video-on-demand, one of the largest catalogues you will find anywhere in these waters. It aggregates a barely-comprehensible 820,000-plus scenes and 200,000-plus DVDs from nearly every studio and niche imaginable, which makes it the place to go when you want selection above all else.

The model is different from the usual subscription networks. A membership unlocks unlimited streaming across a huge swathe of the catalogue, and that sits alongside pay-per-title rentals and outright purchases for the rest. The trade-off is exclusivity and ownership: nothing here is exclusive to Adult Empire, and the subscription does not include downloads, so this is a browse-and-stream harbor rather than a build-your-own-library one. What you gain in return is a selection nothing else in the directory can match.

At $14.99 a month for the streaming side it is cheap for the sheer breadth on offer, though remember the rentals and purchases are extra costs on top for anything outside the streaming tier.

Who should climb aboard? Viewers who prize selection and discovery over exclusivity and downloads, and who like the VOD rental model. Who should sail on? Anyone who wants exclusive content or to download and keep their haul, since neither is the point here.

Bottom line: Adult Empire is the vast VOD harbor of the porn ocean, unmatched for selection across studios and niches. There are no downloads and nothing is exclusive, but for pure breadth and cheap streaming it is in a class of its own.

Adult Empire earns its place near the top of the category: best for Viewers who want the widest possible selection across every studio, via streaming and rentals.
