I know of at least a MS-DOS game, published on Portuguese Spooler magazine, that was using Turbo C++ basically as a macro assembler.

One of the PlayStation selling points for developers was being the first home console with a C SDK, while SEGA and Nintendo were still doing Assembly, C++ support only came later to the PlayStation 2.

While I agree C++, BASIC, Turbo Pascal, AMOS were being used a lot, specially in the Demoscene, they were our Unity, from the point of view of successful game studios.
