Text adventures.

You had to type a command, and if the command was written exactly right, it would do something. "Use torch on tapestry" "Kill Trogdor with acid potion". Any misspelling or grammar it didn't like would present a random error message "You can't do that" or "That wouldn't make any sense"

Thank God for the SCUMM engine with games like Maniac Mansion and Monkey Island where you had 9 fixed commands (icons) and you clicked on items in the world, and items in your inventory to make things happen. Still some challenging and bizarre puzzles, but at least you didn't have to worry about the grammar of the whole thing.

Did I mention the original The Secret of Monkey Island has been remastered in HD, voiceovers added, awesome music, and released both on the iPhone and the PC? Plus there have been 2 followup games (the 3rd one looks awesome), and this summer there is another company who has licensed the rights to produce 3-4 hour "episodes" to add onto the series.

I'm about halfway through beating the game on iPhone.
