4. Loki
Ah yes, the disgruntled brother of Thor. Here's the pitch: Loki, angered by his father's favoritism of Thor, angrily runs amuck in Asgard fighting a slew of foes from his universe. From frost giants to Thor himself, Loki is on a rampage! Simple, succinct, and akin to most action-adventure titles that lend their gameplay mechanics to the God of War style of play; a clever title and voila! An annual-izable franchise on par with Activision's begotten Guitar Hero and Call of Duty alike. To think that such great ideas are simply being passed over in the corporate shuffle to pre-eminence in the industry fills my heart with ubiquitous enmity.
