That's a very interesting one. I know that there have been many different approaches to recreating Stunts. Many of them have been mentioned in this forum. Maybe the best known is Ultimate Stunts, but all are too different from Stunts.
In this particular case, it appears at first sight that the game is much more similar to Stunts because it uses its original 3D models, but it's actually entirely different: the physics are more like that of other car games and the engine is both hardware and software demanding, since it uses 3D hardware effects and if I understood correctly, it's built upon third party libraries (too many dependencies). These things are nice, but I think that, for a recreation of Stunts to stick, it has to be... well... "Stunts". Only a few things can be changed that people would accept such as:
- Make the game run natively on newer OSs
- Allow higher pixel resolution
- Maybe change the collision and physics engine as long as they still appear to be the same (that is, it's not that important if replays are incompatible with the new one, but it is important that the game still feels like Stunts). Changing the engine would allow more practical car design, making the game more flexible
- Allow mods
I've made a triangle drawing function that I could translate to assembly to make it lightning fast, but then comes all the 3D and collision and I fear that will kill me, ha, ha.
