I think there are multiple reasons for lack of excitement.
Imo the biggest reason is that the big companies in the video game market have finally found out the best way to make money. The problem with their strategies is that they are no longer looking to innovate and improve the video game market. They are looking to hold the status quo and make X amount of $ every year instead of thinking about doubling the $ or tripling the $ etc...
It has been 14 years or more since a major player has entered the video game market, and it seems that will not change anytime soon. We can see that MS is content with selling less then Sony as long as they make a ton of money from Xbox Live. We can see that Sony is content with losing the handheld console war as long as they have the PS4. We can see that Nintendo has so much cash reserves that they don't care that the Wii U gets no support and continues to stagnate. We can see that the big game companies EA, ACTI, UBI etc. are fine with yearly games and less innovation.
Reason #2 why Vgchartz is boring is because if you don't join meta threads then you are missing out on a lot. Other then Meta threads you have General, Politics, and Sales discussions to try and keep things lively. So if you don't like General or Politics, that leaves very few threads to discuss with people. Meta Threads are much like the hardcore version of this site, it isn't very useful to casuals. But hardcores get a lot more enjoyment from it then the casual threads.
