Sketchup was the hardest part of the class because I am not very talented when it comes to visual arts. Creating content in Second Life was easier for me. The FaceGen tool was fun to play around with because of all the options it gave for adding details to a 3D face. BS Contact was interesting as well, but felt limited compared to FaceGen.
A couple other games we used for this class were Runescape and America's Army. I appreciated what they tried to do but I thought that both concepts were dated compared to newer games on the market. The look and feel of both games felt quite old.
This was an Immersive Education class at Boston College.
