Lack of content, lack of games they support, lack of participation, etc. Lack of people (again, participation); these are just some examples I can think of. Lack of participation comes from the strict rules they have implemented in their servers. I find it funny that posts start to come around during their "gaming events". I would like to see EVGA get into MMOs, like Elder Scrolls online, starting an EVGA guild, which would be really cool to me.
Eventually the gaming events will die off as well.
