IV is an interesting case because the entire game was built around repercussions for your specific actions, although the only long-term repercussion of doing comically evil things was that you had to spend a bit more time throwing money at beggars and overpaying at the reagent store. V switched to a simpler karma system that mostly affected how badly you were penalized by dying and whether you were able to complete the game. Reputation systems were pretty common in CRPGs starting in the '90s. In practice, though, a lot of those systems just boiled down to "does everyone in town want to kill you the moment they see you or not".
