I remember when free 2 play was called "shareware" and DLC was called "expansion packs"
But seriously, shareware was awesome, You got like the first 25% or so of the game, usually self-contained to some extent, and it was often longer than your average game today.
It wasn't B-grade software either. Wolfenstein 3D was shareware and it was probably the most technically advanced game of its time.
Now your average demo is like 3 gigs and lasts 10 minutes, not 10 hours.
