You simply must read this piece from Penny-Arcade Report regarding Path of Exile. Here’s a sample of the article:
Grinding Gears is basing their game on a crazy business model: They want to make the players happy. This isn’t EA, a company that shrugs off customer complaints by looking at the bottom line; Grinding Gears legitimately spends time and effort trying to track the happiness of the players of the game.
While big publishers suffer losses and blame the economy, mobile games, and everything else under the Sun, maybe they need to consider this “crazy business model”, eh? I dare say it’s working for Valve too.
