Great project!!! It will indeed be very innovative and I love how it resembles WoW so much. Can't wait to see this concept come to testing and play with other people. You guys keep working on it!!
Hey I have all the half life series on my steam. And I have to tell you it's a great game to play.BTW! If you want to play the 1st half life with better graphics for free then go ahead for this mod: http://www.blackmesasource.com/ Half Life has a great mysterious ambiance. And it's pretty much filled up with lot's of action and easter eggs. Each game has also episodes you should try out. VALVE CAN'T COUNT TO 3!
Past Experience: Well, Minecraft got no secrets for me. I'm a INFDEV player myself (quite old player we can say.) I have started to work on community servers since 2011 with staff managing and mainly building. Also have worked for other building team (TToR), but they have stopped the development of the project (this one: https://www.youtube.com/watch?v=Wn8a4WOdDKQ). I also have experience with building tools such as VoxelSniper and WorldEdit.
