Most of my deaths in Rogue Legacy are greed based. Well, greed and old habits. When an enemy drops something in a game, it must be grabbed as soon as possible, right? If not, it will start to blink and then it's gone. No loot for you, fair player. That is not the case in Rogue Legacy, thankfully, as enemies and objects can drop lots and lots of gold. But it is such a common occurrence in games that my instincts are to grab first. Which is not a good idea when there is plenty of time to get it later.
I love when games force me to examine playing habits that have formed over the years. I don't, however, love how much I'm dying in Rogue Legacy, but it sure does make one want to improve.
