While GTA5 ranked as the site's most-played game in its first 30 days of release, Activision's Call of Duty: Ghosts emerged as the single most-played Xbox 360 game for all of 2013, beating out popular favorites like Minecraft, FIFA 13, and Halo 4.
Raptr's results name League of Legends as its most-played PC game of 2013, outperforming rival MOBA Dota 2 and MMORPGs Rift and World of Warcraft. Grinding Gear Games' Path of Exile takes top honors as the site's most-played new IP, while Terraria's 1.2 content update ranks as the year's most-played DLC/expansion.
It's worth noting that Raptr only tracks member playtime across the Xbox 360 and PC platforms; Wii U and PlayStation 3 gameplay is not calculated as part of the site's rankings. Still, the results give an interesting look at how much time players invest in a game after its release on an individual platform, as compared to its long-term popularity throughout the year.
