Coolest game/product you discovered at Gen Con?

[haiiro]

Oodles of cool stuff, but discovered gives it a different spin for me. The two coolest things I picked up that I didn't know about before the con were WotC's HeroScape and a huge, solid metal d20 from Dwarven Stones. The sheer amount of neat stuff jammed into the HeroScape box is unbelievable -- I can't wait to actually play it!
