In a one on one game though I would still recommend following the spirit of the rules and lift all restrictions. In the end it worked out fine and probably would have made the game too long considering we had four people playing. The other players were less comfortable with the no restrictions thing so we ended up doing 50 wounds max, 0-2 heroes, and 0-2 monsters. We ended up having two more players there as well so in the end we decided on playing a four person game, two people per team. It will encourage people to actually paint their models and then rewards you for doing so. In a game with basically no army building restrictions why not make that the only restriction. I thought that was quite a good idea actually. I took my Tomb Kings with me and the only restrictions my friend and I had planned on was no unpainted models.
