Glyph was created to connect developers with audiences, and is purported to be friendly to use from both sides and DRM-free. The platform will take over the responsibility of being the launcher for Trion's titles, including RIFT, Defiance, and Trove (we'll believe ArcheAge when we see it). Trion says that the studio has already handled "more then 10 million gamers" in the past three years and that Glyph will be a great help to pair those players up with current and future titles.
Glyph will also handle games from Trion's partners, as the studio has already begun signing on developers. It will launch shortly after GDC 2014.
