> The effort to develop the engine in the first place probably took multiple people much effort when these games were first developed, and those programmers were paid; reverse engineering is harder and requires more effort and tenacity, and yet we still see a seeming overabundance of fully-functional complete reimplementations. The counter point to this is you are reimplementing the solution. The initial implementation was solving a problem. Which means it took a lot of tries before coming to the solution that you don’t have to deal with when reverse engineering
