Conclusions
Current virtual worldsdifficult to adopt for educational needs
Creation of interactive objectstime-consumingrequires high programming competence
Tutor concentrated on tool instead on didactics

Conclusions
VirtualLife supplements learning with on-line interactionssimplified installationcontent creation
supported by rich interactive object library
web generator facilitates creation of searchable learning materials
advanced featuresdecrease the need of face-to-face activities
