Did you ever notice that now garry’s mod is kinda in the 21-22 centure stage?
Right before the 9th version it was kinda the stone age.
As soon as the 9th version appeared the time went faster, so it gets all the era from the 0000 year up to the 19th century.
The 10th version gets the early 20th century and now is about at the level of 21-22 century!
About some years ago a simple car,
that could move itself was such an achievement, now it look weird near high-tech flying cars
,GIANT walking robots(http://www.youtube.com/watch?v=8bbGdpO-wKk&feature=related)
I dont even tell about the space flight)).
So, what will be next to your mind?
Maybe…the 3rd world war and then fighting with sticks and stones?)))
