Erik from Arcen Games here. Just checking-in to make sure everyone's being civil, and no one has attacked this guy for mixing up one excellent indie dev for another. Glad to see that's the case. (Actually just caught this on our google alerts.
Also AirMech rocks, it was awesome meeting/exhibiting alongside you guys at MineCon!
Great to meet you too! MineCon was great for us indies, we didn't get shoved in the corner like we usually do.
Notch and Mojang were great hosts to have us there. Love those guys.
