I think Pascal didn't got much love from gamedevs for more or less the same reason it didn't got much love from everyone else - there was only a single company with a popular Pascal compiler (Borland) and that self-imploded by trying to chase after enterprise markets while ignoring the masses of developers that made them popular in the first place. For the entirety of the 90s, people who wanted to write Pascal on a mainstream platform (ie. DOS and Windows) had very limited options.
Official SDKs and OS APIs written in C didn't help either too, although that was a minor issue. But still created friction.
Of course with Free Pascal that isn't the case anymore, FPC is the compiler with the second number of supported platforms (after GCC) and architectures, but the stigma and public perception of the language still prevails (for example many things that people laud D and Rust for are things that Free Pascal did for years).
