Currently, I'm working my way through James Clavell's Shogun: A story of Japan, released by Infocom in 1988. So far, it's a sea-faring text-based adventure focusing on the Japan islands that's well written, backed by the IBM Interpreter, supporting plenty of verbage.
Have the first paragraph:
"The gale tears at you, biting deep within, and you know that if you'd make landfall soon you'll all be dead. You are John Blackthorne, Pilot-Major of a dead fleet: one ship left out of five, eight and twenty men out of one hundred and seven, and only ten of those can walk. Little food, almost no water, and that brackish and foul."
However, it can be a horrid pain to get your character to "lie down" at a critical moment, and navigating the first major puzzle is most evil .
Along with Duke Nukem 3D (Haven't played it in 8 years prior to the pat few days). Got to love that ham, the Duke, fightin' L.A.R.D. and the alien evasion robbin' us of our busty women. (High resolution pack is a must.)
And finally, Civilization 4 and Colonization 2: I miss the two-dimensional graphics, though, and the seriousness the first of each has. Now, its not uncommon to get a highly animated NPC to 'prance' around shouting "live long and prosper!" after deciding on peace . . . Brings back bad memories of Red Alert 2 -- Where everything was a self-parody and a joke, flyin' in the face of the original Red Alert and Tiberian Sun (not that they didn't have their humor . . . just not so . . . bloated was it).
