If you're new to the game. Get this one. A great way to play it. It's fast and looks good at the same time compared to the DOS version. Just force vsync to whatever video card control panel you have. And you got a very smooth and fluid gameplay that the old version never had.
These people are lazy asf. Just adjust the frame rate to 10. Use a controller (I'd suggest a DS4 or any Xbox controller) Use the analog as your movement and everything's gonna be perfect now. Check out my video playing this GOG version. A must have seriously. If you wanna see my gameplay just type LaserSauce Retro Archives and check Star Wars Rebel Assault gameplay.
If you want this game to look good on your modern systems. I'd recommend you to download dgvoodoo. Select the Direct x tab, select ATI Radeon 8500 as your main card. Max out the anti aliasing and anistrophic filtering. Trust me, it runs perfectly.
If I had to describe this game. It would be like John Woo's Hard Boiled + Max Payne + Matrix and some Asian horror film had a baby 😂. The atmosphere, the gunfights, the graphics, that intense music, the immersion. I mean what can I say more! One of the best SP experiences I had!
