For some, success is measured in how fun a game is and how much it accomplishes that which it promised. For others, success is all about the cold, hard numbers -- subscribers, units sold, accounts created, concurrent players. Today, Trion Worlds considers RIFT a success on the latter front as well as the former, as it announced that the company is nearing the million sell-through mark for the game.

A unit sold-through means that a copy of RIFT -- physical or digital -- has been sold to a customer, not merely shipped to retail. In an interview with Gamasutra, Trion's David Reid says that the company's $50 million title is doing well with direct competition against established fantasy MMOs like World of Warcraft.

"We're really pleased with what we're seeing. And beyond that, it was a pleasure to see in the latest Activision Blizzard earnings call that RIFT was inquired about when Blizzard announced their subscriber numbers went from 12 million to 11.4 million," Reid said. "You can do some math... we know very well where those 600,000 people are."

Trion is becoming well-known for its aggressive marketing push behind RIFT, which Reid thinks is paying off handsomely: "We know we have a very stick game, we know we are getting a lot of success right now... If in fact the 600,000 players [Blizzard] lost came to RIFT, I don't think they'll be getting those 600,000 people back as quick as they did from Aion, Conan, Warhammer and the like."
