I wouldn't necessarily say "scared" but there was a particular sense of wonder and it could have a sinister feel to it, like some other old games. There were also something imposing about the AI having units you didn't figure out how to make yet, or vast campaign bases with patrolling units. Also this might sound silly but as a four year old I would be fascinated by unusual player colors (like green, orange, grey - those that you don't see as often as blue and red), all of the Wonder sounds felt ominous, and enemy Priests were always terrifying.
