The overall difference in mechanics between Odyssey and Valhalla is not in favor of the latter. In theory, there should be progress, but it is not. And what's more, the game feels worse - it gives the impression of degradation of the gameplay. If growth is noticeable between Origin and Odyssey, then there is no growth between Odyssey and Valhalla. And all of the above follows another drawback - the price. The game should cost 10-12 USD. It is for such a price tag at a discount that it makes sense to take it.
