Tree of Savior is the Second Coming of Ragnarok

"Tree of Savior is being touted as the spiritual successor to Ragnarok Online, one of the most popular Korean MMORPGs to hit the market. The game is developed by IMC, with development being headed by Kim Hakkyu, the original creator of Ragnarok Online. It features something like 80 classes to choose from, and has a jointed map approach to gameplay, similar to that found in Ragnarok. We managed to grab a closed beta test key and check out the game." – Attack On Gaming
