Although virtual worlds increasingly attract users today, few studies have addressed what satisfies virtual world users. We therefore defined and tested an integrated model of experiential system value and virtual world satisfaction. Drawing upon expectancy-value and cognitive evaluation theories, four important facets of experiential system value were hypothesized as determinants of virtual world satisfaction. Structural equation modeling was employed on a sample of 567 users of the virtual world Second Life. Direct and indirect effects were tested and are reported. Theoretical and practical implications are discussed. © 2011 Elsevier B.V. All rights reserved.
