The collection of Warriors of the World has 4 subcategories. Knights, Romans and Knights of Camelot are in the "Toy soldiers" area. Legends is in the "Figures, Statuetes" area.
1.) Knights contains a total of 38 models: 26 models of knights (some in a set with a unique horse), 3 models of horses with serial numbers, 3 models of these horses with a rider, 6 models of the original knights in a different colour scheme (2007 edition).
In addition to these models there are 4 accessory models and 1 dragon, but as far as I know only publisher Epixx released them.
2.) Romans contains 16 models. 3 of these models were only in the set (chariot, ballista, beasts).
3.) Legends contains 14 models. 2 of these models are modified original knights
4.) Knights of Camelot contains 5 models and 1 set with bonus figure.
This entire collection, with minor adjustments in the number of models in the collection, has also been released by Comansi (for Spain), Energy toys (for Italy) and Epixx (mainly Germany and the surrounding area). The models of all publishers are identical, marked BBI logo and do not differ in any way. Comansi and Energy toy released them with the same box design as the original BBI, with the original names and numbers. The only difference being logo on the box. Epixx released them in their own box design, with their own names and numbers.
A few years after the end of production, cheap imitations appeared on the market. The quality, colors and details of these imitations are very low.
