Half-Life is actually a pretty short game and so was most older FPS titles as well. It might only have taken long in the first place because you where a kid back then.Sgt. Sykes said:Sigh, the times when games were 20-40 hours long and speedruns under one hour.
Now the game is 4 hours long and speedrun is 3:50 because most of the gameplay are cinematics and scripts forcing you to walk.
Anyway I love these types of Speedruns that glitch the hell out of the game to do the most impressive feats that Gordon can pull off.
But as long as they don't use cheats like God mode and infinitive ammo and such things it's fine. Scripts are fine for me.
