If you were following a bit of my run up to Gencon posts, you might have noticed that within the last year I've really gotten back into Warmachine with my brother. Luckily for me, I had pretty much hung on to almost all of my minis from the Mark I version of the rules, including Cygnar, Trollbloods, and Mercs (mostly dwarves). Of course that didn't stop me from picking up a small force of Retribution (elves) as well, but that's more of a digression at this point.
We decided that we were going to try to play in the Iron Arena this year at Gencon. We had spent the last year playing between a half and full dozen games against each other trying to brush up on the rules, and we were having a TON of fun with it. Lots and lots.
Let me go over the format real quick, but Iron Arena is a unique way to play the game. Basically you purchase a ticket for the entire day (or days - 2 in our case). You report to the Privateer Press area and register yourself and what state/country your from. This part is important and you'll see in a bit why.
Then you play pick up games pretty much the whole day with other Iron Arena contenders! You can play any faction, any size game, any number of players, whatever your heart's desire.
For each game you play, for every hour, you can report the results, and you end up gaining skulls. You can earn skulls for playing 50 point games (the tournament standard), a fully-painted army, for playing on a scenario table, for playing someone from a different state or country from you, for playing an army composed of forces specifically designed for your warcaster/warlock (known as a "tier list" which basically grants special rules for your army on the condition that you limit the units you can build your army with), and several more things.
You can then spend your skulls on items like art prints, dice, measuring templates, and in the most skull-intensive items, "extreme" alternate sculpts of big models. It's a pretty great selection.
So the strategy here is two-fold. Obviously you want to play a fun list because all these games are for-fun. The other half though is to figure out how to maximize your skull income. That leads into the prep work for the con!
