I don't think a game could ever be too violent. Even if there was a game that was inappropriate/too violent for a good chunk of people, they don't have to play it.
I assume it's the amount of money you paid per hour of entertainment. For example, you buy a game for $60... played it for 10 hours. You paid an average price of $6 per hour.
I've never used the mic in Team Fortress, so I can't speak on that. No one ever insulted me over mic either. Maybe I'm lucky in that regard. Seen a lot of people call other people tryhards or 13 year olds though.
There's a wii in our living room that we still play with every once in awhile. Occasionally, some family members will come over and we'll get drunk as fuck and play Wii Sports (mostly bowling). Shit is fuckin' fun yo.
Pauls_Ego has streamed it a couple of times lately. Though, I'm not sure if you would find his SWTOR streams entertaining. Mostly because he's been roleplaying as a Christian Youtuber known for constantly accusing people of attacking his family.
