CluckAmok, always brings a great version of it to our local con RECRUITs with miniatures and hex terrain. I've tried in vain over years to make a hex map for own 8'x6' table.
Big Red Bat Cave for years. When I saw he had written a set of grid based rules that combined a lot of the aspects of games I like I pick them up right away. I don't have an ancient army, but I do have a lot of medievals.
The rules are great for a multitude of reasons. Don't need a particular scale, basing or mounting system. The grid can be subtly added like I did with small stickers painted a shade lighter or darker. I settled on 6" grids which is slightly larger than two of my 60mm bases wide. It only took about 15 minutes to add them.
My biggest change was to use d10s instead of pulling cards. To the Strongest uses a couple standard card decks with the face cards removed. Personally, I didn't like the look of the cards sitting behind units. It was easy just to put the die back there. They come off at the end of your turn.
The game itself took less than 10 minutes to explain and the guys were rolling without much looking at the rules. They doesn't mean the game is simplistic. It has quite a bit of subtle tactics.
The game itself was a blast. It came down to a difference of 1 Victory point. Just when it look like one flank was going to be rolled up by a flank charge, the general rolled "1" to activate. A failure.
I highly recommend the rules. I will be using them for some Fantasy battles soon.
