Just out of pure curiosity, why can't they put console commands in? Can't they put it in but just limit it, so you can only do certain things like spawn items, resurrect/kill characters, ect just make it so it disables achievements/trophies.
Probably because A) they're afraid you'll break your game (it's not hard to do with the command console) and

the consoles don't really need it. Despite popular belief, the command console is NOT a cheat tool. It is a testing and debugging tool. It can be an invaluable tool on an open system when you're testing and debugging mods. On a closed down system, though, there's no real need for testing and debugging.
