May Game is "Cartoon Action Hour".

Here's how I come up with it.

April (This mouth)
May (Next month)
Blockbuster (May has become the start of the Hollywood's blockbuster)
The Transformers (a Blockbuster movie trilogy)
The Eighties (The time period that the original Transformers G1 cartoon come from.)
D&D (In the eighties, D&D has a slight imagine problem.)
Cartoon Action Hour (Another tabletop role-playing game)

Series is still undone. Come this weekend, I ask Mythic Game Emulator which series, I doing.
