Just had a play on all four of the new games. Pretty interesting.
The Squad game is like an actual, proper game. I died once, but was given another life? I didn't really understand why. I was also disappointed to see that you can't just carry on once you've finished a level. You apparently need another streetpass to continue.
The Battle game is very awesome, although, you will really benefit from tagging people with loads of people in their plaza. My launch console with its five special miis don't really cut it, but I enjoyed what I played. Though I think I might have screwed myself for a while by upgrading my castle!
The Mansion game is a unique take on Streetpass Quest essentially, albeit with real time battles and an unusual tetris shape, floor-building twist. I fucked up really and took the wrong piece from the first mii I streetpassed, so literally gained nothing in the process. I'll have to think harder about it next time.
The gardening game is...weird. I successfully grew a plant, and...that's it? I dunno. I get consistent tags off my launch unit, so will keep playing to see what this is offering, cos I really can't tell right now.
Overall I'm pleased I bought the combo pack. It certainly adds longevity and interest to the Plaza, even though it appears as though you only get 4 hats per day.
But yeah. Sort out those streetpass station Nintendo! Thanks.
