The last update wasn't huge, but overall the game has a good bit of content and playability. Personally I'd say give it a try now (I find it good so far). There is a debated section with the older sister, but the rest is fun/interesting. Mom, younger sister, and side stories all have a nice amount of content (though it will never be enough ).Played this when it first came out. Are the updates still tiny?
Hope that helps
