I created a quite similar OOP system for C around 1995 (as I guess did most programmers at that time who were fascinated by Objective-C), classes were implemented in DLLs and were loaded on demand, classes were objects themselves, the tree of class objects could be inspected (e.g. runtime-type-information and -reflection), and the whole system was serializable - this was for a PC game (https://en.wikipedia.org/wiki/Urban_Assault).

It looked like a neat thing at the time, but nothing a couple of structs with function pointers or a switch-case message dispatcher wouldn't be able to do just as well, definitely not something that should be the base for more than one product, and most definitely nothing that should have survived the OOP hype of the 90's ;)
