"Go play the original" doesn't account for a single point in my post. Let me break it down for you - what we're discussing would theoretically have:
- Better support for modern systems (widescreen and windowed modes)
- Possible to port to a new OS if the original game is broken by Windows 10, or any newer OS
- Mods
- Easier and more versatile level editing
- Multiplatform support
None of those things are addressed in saying "go play the original".
