The Engineering room in Star Trek TMP definetly looked spiffy, as did later Star Trek designs. However the TOS design did look most realistically like a power generation room / reactor-room.
This design kind of has elements of both TOS, a little bit of TMP, and some ENT characteristics which I kind of like...
BTW: It's a modification for Elite Force, which takes place onboard a Federation-Class Dreadnought...
