The classic original.

The good old days when crits were crits (both for and against you). When being dumb meant you were truely dumb, having low charisma meant you were shunned in town. When there were over 20 ways to end up with a character that could break the game (aside from when those rare criticals happen against you).

The game where you didn't even have to kill anyone to win the game (science, speech, charisma, luck, doctor, repair and the right dialogue options).

Fun game, check out the NMA forums to find unofficial patches too.
