If I was in charge of HTC's marketing and distribution I would:
Get the game on Steam.
Steam has on average 5 million people logged into and playing via their distribution service.
I would use Steam's Greenlight service which gives their user base the ability to vote for games that they want on the service.
I'd make Aces High free 2 play with limited access to the arenas. Make scenarios and LWM only available only to subscribes to: 1. Prevent new players from spoiling scenarios, 2. Entice the free players to pay up.
