Here's a game myself and one of the other local guys had a few weeks ago. Unbound is actually a pretty good way to play large games. The activation order is very tactical, and requires a very good grasp of your strategy. The game moved faster than I thought it would, and playing with that many models on the table wasn't that bad, to be completely honest.
We went all out, and usbprime (my opponent) pulled out the stops, and built us a barn for the Barn Stormer scenario.
We decided to call it a draw after 6 hours with not a single warcaster dying. Skarre, and Stryker both took a bit of damage, but that was all. Holding the barn flip-flopped between the two of us over the course of the game, and no control points were scored.
Would I play a game this big again? Yes. Definitely.
Without further ado, Unbound: Fully Painted.
