Described as part real time strategy, part role playing game, GAMEVIL's Plants War is the most adorable game to offer "intense real-time tactical strategy" I've seen in months.
The game takes place on a post-human Earth, where animals who were left behind on the (mostly) barren planet have begun taking over the one remaining holdout of lush greenery and water – Dryad Forest. Enraged by the animals' exploitation of the forest, an army of plants (using a magical power source provided by Lake Naiad) band together to stop the animals. Of course, a raging battle ensues.
Players, when starting a new round, can select their "hero," with additional/enhanced heroes available for purchase using two types of in-game currency: gold and leaf.
