  Virtual reality (VR) games are gradually becoming more elaborated and
feature-rich, but fail to reach the complexity of traditional digital games.
One common feature that is used to extend and organize complex gameplay is the
in-game inventory, which allows players to obtain and carry new tools and items
throughout their journey. However, VR imposes additional requirements and
challenges that impede the implementation of this important feature and hinder
games to unleash their full potential. Our current work focuses on the design
space of inventories in VR games. We introduce this sparsely researched topic
by constructing a first taxonomy of the underlying design considerations and
building blocks. Furthermore, we present three different inventories that were
designed using our taxonomy and evaluate them in an early qualitative study.
The results underline the importance of our research and reveal promising
insights that show the huge potential for VR games.
