  In a recent paper [arXiv:1302.6382] Emparan, Suzuki, and Tanabe studied
general relativity in the limit in which the number of spacetime dimensions D
tends to infinity. They showed that, in such limit, the theory simplifies
notably. It reduces to a theory whose fundamental objects, black holes and
black branes, behave as non-interacting particles. Here, we consider a
different way of extending gravity to D dimensions. We present a special limit
of dimensionally continued gravity in which black holes retain their
gravitational interaction at large D and still have entropy proportional to the
mass. The similarities and differences with the limit considered in
[arXiv:1302.6382] are discussed.
