Essentially what this is is a chain of limitations put on the player with the intention not to win games, simply to improve macro. All races are in stages, and the player must meet certain criteria to move on to the next stage. For example, Tier 1 for Terran is 'marines', no geysers or nothing, and you don't even have the 'power' to look at your opponents side of the map, only basic minimap army controls.
I want your opinions on this, because I'v been using it for a while, and I'm absolutely loving just how freeing it feels. I don't have to worry about wins and losses anymore, just on macro and keeping my money low.
