Stellaris: Toxoids Species Pack

"The overall gameplay experience is engaging for most players, complemented by the species pack that enhances gameplay depth and introduces a new race focused on mystery and transformation, while the well-written storyline in the DLC adds to the enjoyment; however, numerous bugs significantly affect the experience, the mechanics leading to planetary pollution and toxicity detract from gameplay, and many players criticize the civics as terrible and in need of reworking to enhance engagement."
