IMO, summer affects your impression mostly - people have to relax sometimes, they aren't robots with power elements (batteries or such stuff). If you feel burned-out, depressed a bit or very tired of same routine every day, you must get away from everything and get new experience, visit interesting places, spend more time with family, important friends or just sit a alone nearby a river and think about positive thins in RL, make up plans. I know the drill, because I've experienced a few times. I guess it's hard to understand this until you get caught up by exactly same or almost similar problems.
Patience and eveything will be fine... in autumn, let's hope. Cheers!
P.S.: of course, there can be other reasons... My explanation doesn't really fit to all. I'm not trying to sumarize overall situation, just gave an example.
Edit1: By the way, what did you mean saying 'they're playing
Arma 3'? It isn't released yet. Will be in 2012 summer, though. You've probably made a simple mistake while writing a new thread very late at night
. Nothing, it happens.
