Well, first of all, these are both badly fucked-up industries. Fucked up in different ways, to be sure. Some things are the same. For one, designers don't get no respect. And you notice I had nothing to do with the 2nd edition of the Star Wars RPG, even though the game is basically my rules rewritten to eliminate all of the jokes.
Computer gaming works more or less the same way.
Unless you're Sid Meier, you don't get cover credit. Still, none of these guys get much credit. A major difference is the sheer scale of financing. That's pure development expense. Contrariwise, the money is a helluvalot better, too.
