It most definitely is not lmao it was almost 3x the content. Did you miss stuff somewhere?
So there's the added Brandy content, some you can do before the road trip other you do after and the after includes a couple new repeatable options like taking her home or in the school bathroom at lunch. You have the whole road trip, which is a good chunk considering how long it's been since we had a neat little adventure arc (the last major one was with the goth baddy in the cemetery). This also unlocks new repeatables to Cassie which involves what... 5 animated scenes? Or was it 6? Then you have the game night with Ashley that sets up for a number of repeatable options with her while laying ground work for a future update, as well as movie night with Lesley that also directly lays ground work for a very clear update as stated by the in game quest. Typically most updates do not include this much content lol. I could also technically say Sunny's arc is a good adventure but like... Cassie and Sabrina's arc are the only ones that actually have you leave town :o
