The converse is also true, however - that detail and research can also be detrimental to an RPG. The classic example here being Phoenix Command which used computer models to simulate gunfire. It really is an RPG for wargamers.

These days though - I'm a narrative and rules-lite biased person. But those kinds of rules are only good for genres the GM is alread familiar with and aren't great for introducing old-school style players to roleplaying. However - they are good rules for writers and drama folk :)
