But if access to the console was provided via DLC--completely optional to users--would that not circumvent the problem above while providing 360/PS3 users with PC freedoms?
The idea is this:
1. You download the DLC.
2. You activate the console by holding down a button for 3 seconds, or perhaps through a menu instantaneously.
3. If this is your first time opening the console, you get a confirmation dialogue not unlike the first time you picked a lock. It will inform you that the console is an advanced feature, etc. and could ruin your gameplay experience. (Something you'd also read in the summary description for the DLC.)
Note that I've split the NO answer into PC and 360/PS3 answers, because it's likely that PC players will hate the idea of DLC catering to console players.
Edit: Added the option "YES. -- From a PC player."
