The aim of the article is to find the appropriate legal construction, based on the Polish law, explaining the core of virtual reality items sale agreements. The main legal problem of such items is, that they exist only in computer games, which are mostly played through the Internet. Considering the legal nature of virtual reality items, they must be seen as works in sense of the intellectual property law. Is there a link between "the world of a game" and the real world? If so, what are the criteria of such connection? Virtual reality items sale agreements can be entered into either with the creator of a computer game, or with another player. What are the legal consequences of these agreements? Do they differ from each other? The author tries to find suitable answers to the abovementioned questions.
