Best PC games of the 90s?

Too much to name off-hand.

I'm surprised nobody mentioned Shadow Warriors, Blood, Jagged Alliance 2 and The Last Express.

Colin McRae Rally

Transport Tycoon Deluxe - Chris Sawyer - 1994

Flashback - Delphine Studios - 1992

Has to be command and conquer?

@pikachewbacca: doom

Screamer 2 - Milestone - 1996.

As a child of the 90s, the question is not so easy to answer.

But for me the best in genre were:

Adventure = Day of the tentacle

Shooter = Duke Nukem 3d / Blood

Racing = Need for Speed

Sim = Anno

RTS = Age of Empires

And last but not least

MEGA LO MANIA
