Yes, Worms is a classic turn-based strategy game series. Cute, loveable worms, with a ton of deadly weapons at their disposal. The possibilities are limitless. Check out

As for Worms3D, I honestly haven't played it a whole lot. The 2D ones were way better, and W3D just didn't hold my attention for very long. I didn't really notice any bad language, but I do believe there are a few crude remarks. I'm pretty sure you can avoid them, though.
