A very, very fun game if you understand the mechanics. Tips for some newer players. Don't waste energy if the enemy has placed down two or three cards and you're losing by 200 or so points. There's no point unless the cards you're placing down gove energy, or upgrade you in some way. Don't always press end turn. A common way to get people to waste energy is to place three cards down, but not to end turn. Then you remove your cards, assuming they have ended their turn and they waste useful energy
