A Letter and a resume are in a different format. Books and movies are on a different format. To then tell me I’m having a subjective view that a tabletop version and a video game version are different formats? That’s just lunacy.
I think marajango's point was that a single ruleset may work reasonably well for both P&P/tabletop and computer games - with some notable exceptions/modifications of rules (mostly due to existence of save/load functionality in computer games). And indeed, there are lots of good games based on such (not necessarily just D&D) rules.
