Ok, i couldn't resist and spent some time replaying the game.
And even today it's always a good experience, confirming that it is really a masterpiece for the ages.
I even noticed before playing that now can be found an unofficial patch, that solve some problems that were never fixed by Firaxis :
http://www.civgaming.net/forums/showthread.php?t=7511And i had no problem at all with it during all my relatively short game .
As it's been years, i got a tiny planet on the lowest difficulty level to get a not too long game and relearn the game mechanics.
Surprisingly i remembered them without a problem, despite all those years.
Used the Peacekeeper faction and ended by uniting every remaining factions behind my UN rule with a diplomatic victory (considering i was the only one at this low difficulty level to have a dozen of missiles and could start building air assault troops , it helped the acceptance)
I had to bribe Deirdre for a ridiculously small amount of money as while at peace she was not that a fan of mine as i refused nearly everytime her request for some of my advanced techs.
Too bad neither Santiago and Sister Miriam made it to the end, they were early casualties from other factions warmongering.
I forgot the book system in the end scores :
"For i have tasted the Fungus, or why Brother Lal can't blink".
If you question if you should replay SMAC/SMAX or not, dont waste time thinking about it and just go and replay it, even by today standard it's always one of the best 4X in the Civ genre and you'll always have lots of fun.
