There are a lot of great gameplay concepts from the old days in
(too short to understand them, but helpfuls for
remembering these games)

A lot of the concepts where great, but dont show up a lot anymore in games,
such as the click and point adventures,
platformers and sidescrolling shooters.

I think someone posted this some time ago. Its funny because I just played lemmings earlier today.

lol, i remember playing a few of those games

"Knights of the Sky" was left out. That Amiga game consumed many hours of my life. Also missing, "Colonization", which was the inspiration for my current game, "Territory".

"SWIV" still amazes me to see how much graphical material was packed into one 880k floppy, to run smoothly on a 7Mhz cpu with 2 mb of ram.

"Cannon Fodder" was as addictive as "Lemmings" and should be revived.

"Defender of the Crown" was redone with modern graphics by Cinemaware.
