I had an old account a while back in August that I lost due to a computer virus. And did not bother about making a new one until yesterday due to being busy the past several months. But it seems to me that the forums here have been less active than what I remember. So has there been a decrease in activeness or is just me?

Just no new Fallout or TES info. Once Fallout 4 gets announced, expect a huge boom in activity. TESO boards were busy during the beta but even now that has died down a bit.

Forums for the new upcoming games (Wolfenstien, Evil Within) are very quiet right now.
