These games may have been found already amidst the 280 or so pages, but I wouldn't know how to look for them and I have so little go go on.
This is an old game, 80s I do believe, that has the player in a first person rover of some kind within a polygonal, multicolored game world. Movement takes fuel, and running out of fuel is an end game, and in my youth I'd never gotten significantly far in it despite my repeated attempts. I want to say it was possible to fly, or find a flying machine, but I cannot say so with certainty.
The other was an adventure game, you find yourself in a blazing desert, and must search for items to survive. It was a parser-driven game where you find items such as rope, and typing 'help' summoned up the line "God helps those who help themselves". When you died, as you often would, the final scene is that of a gravestone with RIP on it. I saw someone play 'Dungeons of Daggorath' recently, and it conjured these fragments of memory from when I was very young, which now consume me as to their full context.
