We should begin by saying that there's nothing particularly wrong with Funky Barn as a game. Honestly, there really isn't. Millions of people enjoy FarmVille and there's really no reason why those same people wouldn't enjoy this, too.
You get to use the GamePad to drag and drop your various animals, crops and bits of goofy 'egg robot' machinery wherever you fancy.
You get to stroke your animals to make them happy. It's the familiar method of play that we've seen over and again on the Wii and there's nothing particularly noteworthy that stands out.
So far, so average, but it's the non-gaming elements that ruin this game. Trine 2 has proven that great titles can be eShop-only and can be released at a great price. Funky Barn looks like a glorified 3DS game and plays like a run-of-the-mill farming sim. That would be fine if it were priced accordingly (that is, under a tenner). As things stand, it'll set you back three times what would be appropriate. It's utterly ridiculous.
This game should never have been released as a physical product, but even the eShop download is massively overpriced. We are, admittedly, at an early stage of the eShop, but common sense has been doing the rounds for a good few millennia now.
