Path of Exile, a PC Action RPG, entered open beta today. The servers were wiped clean of all closed beta characters just a few hours ago, and there should be no more character wipes, even when the game officially launches. While similarities to Diablo II and other ARPGs can be clearly pointed out, Path of Exile stands apart from the crowd in several ways, including its unique skill system where skills are attached to gems (not the characters) and can be modified with other gems.
