We get that exact same look from his brother and a lot of other players. Hahah.
Tau, Dark Eldar, and Necrons are my style.
He is an IG, Imperial Knights, and Admech/Skitarii man. Only plays IG but says if he had more cash he would start those armies. His brother is a Chaos Space Marine and Space Marine player (also the youngest of our gaming group) and regrets not picking Spezz Marines over the chaos marines though would collect and play both if he had cash. We also have an Nids and Ork lover who isn't overly fond of the Imperium either. Although he doesn't take our hard stance on Space Marines. Finally another guy who doesn't have the cash to play says he would play Tau as well. Most of us just find the Imperium too stupid and the majority of Space Marine chapters too derp. Uh sorry if that offends you. I know it triggers some space marine fans.
We're a fairly unusual group in that regard.
For the record I'm both lactose intolerant and have fructose malabsorbtion. Ice cream and a lot of sugary stuff are simply out of the question for me since even a small bite has usually more sugar than my daily limit will allow. I can and even have to have sugars, but only a very small amount at a time spread out through the day. Definitely a strange person by most accounts. I have to eat a very unusual diet or take pills that can help me eat stuff with lactose in it. Either way.
