I still enjoy this game from my youth many years after.
For those having trouble launching the game on NG launcher, I'll tell you what I did>
-Removed my current version of NG Launcher.
-Downloaded newest Version of NG Launcher.
-Proceeded to restart the game multiple times, like I did when the glitches happened when I was younger.
Cheers, and keep this era of pc gaming alive in our hearts!
