Sorry Aedrelic, I don't mean to disrespect your vote, I meant that the inclusion of multiplayer co-op should not interfere with your single player experience, much like Baldur's Gate, so it's addition would be "irrelevant" to your experience. If it DOES interfere, by all means it should NOT be included. But I have a hard time believing the addition of a relatively simple style of co-op would interfere or be that hard and expensive to implement, as Hypevosa said. There must be something else that's holding Obsidian back- maybe security issues?
