The goal of this game is to count upwards from 1 in Roman numerals.
But once someone either posts an incorrect Roman numeral (for example, VIIII instead of IX for 9) or posts the wrong number (for example, posting X after VIII instead of IX), the count starts over from 1.
Let's see how high we can get!

I’ll start this off:
I
