Probably one of my favorite memories has to be when I completed the original campaign on Dungeon Defenders on nightmare hardcore for the first time. Constant losses and challenges to figure out how to survive the dragon ended up in celebration as we aimed our weapons right at it's head. We then proceeded to goof around with portals guns way too much and lost many many maps. Was fun though!
Can't wait to do it again in Dungeon Defenders Awakened! For Etheria!
