There haven''t been very many games out there with holiday themes. They are tons of books & movies surrounding Christmas, Halloween, etc. Why not have a game with holiday themes?
I was thinking of maybe a 2D or 3D Action-Platform game where you control a guy who travels through numerous worlds, each with a holiday theme. Including New Years, Earth Day, Be Kind to Animals Week, Easter, & Elvis Presley''s birthday.
There could be exclusive items & enemies in each world. Like snowmen in a Christmas themed world, old women knitting sweaters in Mother''s Day, or turkeys in Thanksgiving.
