I keep seeing folks use the term "progression" here on the forum, often in phrases like "vertical progression," "horizontal progression," "linear progression." I'm not sure what all these terms mean. I have a general feeling that it refers to some sense of improvement in one's character as one plays the game (i.e., levelling up, unlocking and improving skills), but beyond that, I really have no idea what folks are talking about.
Can someone more learned than I explain these terms to me? Or do they mean different things to different people?
