I had a fun experience last week during the local FLGS game night. since it is a communal event no one wanted to split off to learn Mage Wars, so I suggested a 4 player intro game. We started with a 20 minute intro to go over some of the basics and then hit the ground running.
It went a lot better than I thought it would. One of the advantages was that they got to experience what the other three players were doing on their turns, ask questions and get explanations while other players were going and it meant we had a good pace during the game.
We got started later than I wanted two and after about two hours it was getting late so we called the game.
Overall I think the format worked out well for teaching the game and I look forward to getting more players to try out the game.
