But... you're a Star Wars fan, of course you might dream about Star Wars. The MC is clearly no fan of D&G (so far). That's why it would be weird for him to have a dream about it, especially a dream with seemingly accurate details like being able to play a bard.
The original D&G session was shorter than some of the dream sequences we've had, I don't see why a hypothetical new session would be much longer.
And again, I despise the dream sequences we've had so far. They haven't given us one lick of character insight. They've been nothing more than gratuitous spank material. And frankly they were bad even at that, managing to make Josy, Cathy and Jade seem less appealing for their efforts.
To me, it's no comparison. Just seeing Jill join the trio as a friend to play a quick, goofy game seems likely to tell us more about how these characters view each other than we'd ever get out of a BaDIK dream sequence. As I said, I don't want to drag this out to a major feature, but as a quick diversion I think it would be great.
