Camelot Unchained continues its foundational principles series of dev blogs with entry number 11, in which Mark Jacobs talks about what exactly constitutes a sandbox game and the philosophy behind the sandbox elements in Camelot Unchained. He starts off with a clarification that "CU is not a true sandbox MMORPG" because "a true sandbox MMORPG would allow the player to build out his stats, skills, alter the world, etc. without most of the fixed conventions and limitations that are found in CU and most other RPGs." Regardless, Jacobs believes that his studio "can learn from and adapt the concept of [sandbox games]."
Jacobs goes on to talk about how and where he decided to implement traditionally sandboxy elements into Camelot Unchained and where he decided it was best to go a different route altogether. For instance, he argues that "in a true SBRPG a player's actions within the game would dictate evolution and progression." Jacobs claims that while CU earns some "sandbox points" because of its relatively unrestrictive class system, it loses some simply because it utilizes a class system. He spends the rest of the post running through the game's list of features and explaining the rationale behind the sandbox elements (or lack thereof) in each one, so if you want to get into the nitty-gritty of Camelot Unchained's sandboxiness (which is now a word), settle in and read the full post at the game's official site.
