95% of the times in the hardest setting. The other 5% is one or two difficulties lower than the highest one, VERY rarely the default one (Applies mainly to genres that I am not that expericed with, such as RTS´S and fighting games, the rare time I play those). Also if playing in the highest difficulty is requiered to 100% the game, I have even more reasons to play in the hardest one.
Me loves challenges. I dont like the games going easy on me, if they are difficult enough to kick my ass until I kick it´s, then so be it (The exception is in RPGS. You know, that one moment where you are level 100 and the enemy is level 20 or something that like and you kill them by looking at them LOL). I also refuse to ever, EVER, E V E R play in a difficulty thats below the default one.
