I have uploaded an epic 2 hour length discussion about Gruntz and play guide on youtube. This is part one and is an overview of the terrain and a start to the game.
I am playing Gruntz in solo mode on the base station terrain, using the card based mechanism from the optional rules section of the hard copy Gruntz 15mm v1.1 book. This allows me to demo the basics of the game without an opponent and I talk at length about various aspects of the game. I also raise the importance of having matched pairs of colored dice to improve the speed of play.
