Blobber is a slang term that is used loosely to refer to first-person party-based RPGs in which the player controlled party is not represented as a distinct visual entity in the game world. As such, the game must stay in first-person view at all times within the game world (so that the camera can never be pointed at the party). Functionally, this means that the player's party always stays together and moves and acts as a single unit. No member of the party can be separated spatially from the rest, so, for instance, one party member cannot be commanded to walk down a hallway while the rest of the party waits behind. Thus, the party only has physical presence within the game world in the forms of walking around (i.e. having legs), swinging weapons or casting spells (i.e. having arms), and staying glued together as a solitary mass (i.e. being a blob). This artifice came to be called "a blob with arms and legs" and games that used it were in turn called "blobbers".
