It’s dawned on me that several things that make BF2142 really not fun all stem from the same source: exhaustion. When you’re tired, your attention span and patience are severely reduced – this leads to you making mistakes (such as being knifed) and it disables your ability to positively deal with failure (ie. you blow up and get very irritable when you start losing).

I’ll list the in-game symptoms I think stem from exhaustion. Look for these things and realize at that point that you’re tired, that you’re making mistakes, and that you’re really not having fun anymore. Call it quits and have some sleep.

Common in-game symptoms stemming from exhaustion:
- being knifed (reduced spatial and tactical awareness is a well-known symptom of exhaustion)
- being extremely irritable with small things (ie. blowing up when your expectations are not met, cursing, yelling at people)
- sitting back and sniping people (your body can’t produce enough adrenaline to keep you sustained through the mentally and physically intensive close quarters combat)
- shooting your own team-mates (slower thought process and less control over instinctive reactions)
- blaming your team mates for doing things wrong (this is related to irritability – you are trying to find the cause of what’s gone wrong and you want it to end – there isn’t anything wrong with acknowledging that your team isn’t very skilled but what is wrong is the blame and negativity you’ve coupled with this fact)

There's nothing really new in this post but I'd just like to raise the fact that people need to learn themselves -- learn what happens to you when you're exhausted, learn to recognize those symptoms, and understand that it's not just you "playing like crap tonight" -- your body is telling you to quit thinking and get to bed.
