use the free channels to promote the game, facebook for starters.
i joined this game called vega conflict awhile back becouse i got loads of invites through facebook from friends and it looked cool.
i played for 3 days, the game was rubish..but during those 3 days i spent aprox 50 dollars on coins to make things go faster in game. Now VEGA are advertising through facebook + u can play it through facebook.
im just saying..FB got me into the game + made me spend money on it..all becous of some fancy grafics and facebook.
