Would I recommend you buy Little Dragons Café for a child at its current price point? Absolutely not. There is plenty of content and it's a decent game, but there are a lot of other games that are on-par with this one that are selling for less than half the price. Until the price comes down, I can't in good conscience recommend that you buy it, and that's a shame.
Aside from those differences, the game… is basically Terraria. Unfortunately, the game doesn't have the massive variety and polish of Terraria's crafting system, doesn't have the interesting biomes of Terraria, doesn't have the crazy enemies of Terraria, and it doesn't make allusions to Lovecraftian horror. That isn't to say Dig or Die isn't fun. It is. I had a legitimately good time playing it, and that should mean something.
The gameplay of Ride 3 is fine. There is a ton of content. If you’re a fan of the series or racing games in general, then I would expect that you would enjoy this game. However, the game is practically turning newcomers away at the door, is encouraging grinding drag races over practicing to improve, and has some slightly suspicious AI behavior at higher levels
