I play within the game's meaning. If I'm playing Batman Arkham Origins my job is to kill the other people and if I can save my own team mates but at the end of the day my objective is to take out the bad guys or enemy gang and win the game. I'm not going to help my team stay alive when I can single handedly wipe out the enemy on my lonesome. Does that mean in real life I'd be so callous? Maybe depends on how much I like the guys I'm working with or how important they are in the grand scheme of things. That being said I love when a team can pull together and absolutely wreck house.

On Payday 2 it's a cuthroat ordeal. I'll help you if you help me and we'll all get out of there together. However if you do something stupid and I have to risk my own neck and the mission to help your ass then I'm more than likely going to let the cops cart you away. It's a matter of what is practical.

In Dragon Age Origins I play a character normally who is likewise practical like the previously mentioned. I will gladly help out anyone but not at the cost of harming my own team or the kingdom. I'm not going to help out the templars half the time in the second game because half of them are xenophobic and those who aren't I tend to help. That being said I'll still gladly take out my sword and put it in a mage's guts if he's going crazed. I took over the throne as a human noble warden so I can have a close hand in what the queen says and not just be 'warden commander' I am King Consort, Lord of Amarathine, slayer of the archdemon, and Commander of The Grey Wardens friend to the elves and dwarves alike. That kind of thinking is what made me constantly pick the little prick that backstabs you in the dwarf origin noble story for the guy stuck in his old ways so badly he'd do worse for the dwarves than the little prick. You can't go forward if you're looking backward less you trip or go extremely slowly.

In Left 4 Dead 2 I play it smart I pick my spots and I am not afraid of outright ditching teams if needed to win the round. But that's something I wouldn't do in real life unless there was no way of saving them. In real life I'd do all I can to help out my team because if they die that's one less gun helping me even if it's less food in my belly. I would prefer being hungry to not being safer any day. 

In Borderlands 2 I'm not stingy with stuff unless it's stupidly rare and will be willing to give a weapon I don't need away. I'm going to help my team and I'm not going to ditch them because we work better together than we do alone. That's just common sense.

On the other hand I side with the imperials in skyrim while carrying and hording stuff for my own hubris like some sort of dragon.

In command and conquer I'd prefer not to lose men but winning the mission takes precedent and if I need to send a wave or two at the enemy then so be it. I'll do my best to find any other way around doing and my turtle style of play reflects that. Wait till I'm the strongest then come out and go all in or nothing. 

I'm sure you're seeing a pattern here. I'm a guy who prefers practicality over flair. I'm a guy who prefers survival to team spirit unless it benefits me otherwise. I'm the guy who looks at the grand scheme of things and makes what I believe is the best possible choice for victory in the end. And I'd say in that regard my play style in games reflect who I am despite the fact there are some things I do in games I'd never even consider doing in real life. Like selling people as slaves, murdering towns of completely innocent people, brutally gunning down someone for their shoes, etc.
