From wikipedia:

...approximately every 14th full moon will be a supermoon. However, halfway through the cycle the full moon will be close to apogee, and the new moons immediately before and after can be supermoons. Thus there may be as many as three supermoons per full moon cycle.

Supermoons happening in quick succession is not terribly uncommon.

"The stars are aligned for this game. Literally."

The use of "literally" as a worded exclamation mark is bad enough, but if you're going to make it its own sentence it had better be accurate. The only possible way that is accurate is if it's a non sequitur. Or, you think the moon is a star, and even then a supermoon has nothing to do with alignment, only proximity.

On your first point, dictionaries all over already accept "literally" has also become a mark of hyperbolic comments, as opposed to just the original intent.

On your second point, if the Moon were a star, the full Moon would have Sol, Earth and the Moon "perfectly" aligned.

The phrase "the stars are aligned" never referred to actual stars actually being aligned in the first place, it means the astrological conditions are (perceived to be) good.
