Yogscast's Simon Lane is probably one of the most jolly of the Yogsbunch from what I've watched, but surprisingly they drop the ball on this one. It's Simon Lane himself, not his dwarven persona with the Celtic accent, and the All Star Theme isn't their original composition Diggy Diggy Hole, nor is it the Yogscast opening theme, which also happens to be the opening theme for the radio play version of "Half-Life: Full Life Consequences", but a knockoff of the former. In a game that's prided itself on kicking recreations of the original songs and superb VO, the surprising lack of dwarven joviality is a bit... eeeeh. I mean look at his appearance in Dwarves!? and Awesomenauts! That dwarven personality just oozes charm!
I'm going a bit Polygon though. Thinking about what should have been, not reviewing the project at hand. Simon's still as jovial as ever, the vehicles are well done, the cart is a wooden dog racer, the boat looks like Link's ship from LoZ: Wind Waker, and the plane has a pig motif and center to the design is a vectorised image of Honeydew, what's not to love?
Oh and you contribute to charity too. Who doesn't love that?
