Echo Delta is a hybrid strategy game designed by Clever Trick shown five years ago at Nintendo’s Spaceworld event. The game has players rush to raise a sunken ship with an armored submarine called Scout. Using Scout you can pick up resources and defend the core which mines resources at a faster rate. If you collect enough energy the ship will be raised and everything is golden. Nintendo chose to cancel this game’s release on the Nintendo 64, but it looks like a complete version of the game popped up on eBay. The price? $1520.
