Infinity Engine (Game engine)

Infinity Engine is a game engine which allows the creation of isometric role-playing video games. It was originally developed by BioWare for a prototype RTS game codenamed Battleground Infinity, which was ultimately re-engineered to become the first installment of the Baldur's Gate series. BioWare used it again in the subsequent installments of the series, but also licensed the engine to Interplay's Black Isle Studios.
