Erm not true. None of those games were off the self plugins as far as I am aware :D We of course look for concepts for games everywhere (suggestions from you guys, other servers, games outside of Minecraft). When we bring a game to CubeCraft though we write it ourself, most games aren't designed to work on our systems or on a scale like we need them too. Reasons like these are why we had to take Creative down and re-do it. That was originally based on an "off the shelf" plugin but as more and more people played on it it became unmanageable hence why we re-made it.
