Hasn’t that always been the case with the warioware series? The games are always a wild mix of off-the-wall mini games that often don’t stick the landing, but for people that enjoy the series that’s the exact charm of them. I would guess if you’ve already played and enjoyed a few games from the series you’ll feel much the same about this one. I’d just check reviews to make sure they haven’t wildly changed the format in a way you’re not interested in, but otherwise Nintendo has been pretty consistent on what to expect with this series.
