I originally found this game on another forum, and I rather like the concept. Kind of a fun way to build one's vocabulary too.

The idea is that you take the last letter of the word above you and create a new word that starts with that letter. However, the main idea is that the word must be 6 of more letters.
Example:
P1: Misha
pP2: Perspicacious
P3: Salutations
So the first word: Voluminous
