You're almost there! Here's a slightly polished version to make it flow even better:

What's Next? A Life-Size Game is already packed with fun, bringing everyone together for the action.

But how about we take things up a notch? Enter the Social Skills Add-On!

Think of it as a bonus to the original game—adding extra tiles and fresh challenges to keep things entertaining every time you play.

It’s the ultimate add-on for endless fun, bigger laughs, and, of course, perfect for everyone to enjoy—together!

To use, replace the original tiles with the Social Skills tiles of the same number and play as usual. Note that this set does not include the base game, which must be purchased separately.
