I'm both playing the games, but mostly I'm very passionate in modding and creating addons. Did a few in the past for FSX, and in Arma I've done an single player adaptation of the DayZ mod called Day of Survival.
As I was in a short one week long holiday last week I got an idea to make a short RTS mission for Arma 3. Short translated in a full Saturday and half of Sunday of codding (Arma SQF scripting is similar to Java), but at first play I knew I hit gold. It was really balanced and fun to play.
Monday I left in a 5 days trip to Rome an then when I got back kept doing some updates. Sunday morning I got the crazy idea of taking part in the Make Arma Not War competition that was closing on Tuesday so had few time to make lots of neede adjustments.
