Ragnarok Online
The game is considered a spin-off to the original game in the series, "Ragnarok Online". However, unlike "Ragnarok Online", which is a massively multiplayer online role-playing game, "Ragnarok Tactics" is a tactical role-playing game, playing more similarly to "Final Fantasy Tactics". However, elements of the "Ragnarok Online" universe are still present, such as similar settings or the fact that crouching/sitting can restore character's health.
