Sense of Wonder Night
Gamasutra has a recap of the TGS 2008 Sense of Wonder Night, the event that was created with the ambition of bringing unique game concepts to light. While some of the concepts were little more than good ideas and not working games, the ideas themselves are still interesting.
Reading the recap is a better way of learning about the games than actually being at the event was, as the sound setup was poor and you could hardly hear anything the translator said if you weren’t sitting in the front seats. I left halfway through it, and missed the most interesting games it seems. More on TGS later.
