Watch UFC, yeah that's how i fight.
I am a striker over a grappler, but have been known to apply an effective choke hold.
I tend to control all RL fights, leading my opponent where i want him to go with faints and light techniques that arent designed to damage but to move my opponent. Until the time for the KO blow comes. Usually a right kick to the thigh, followed by a right cross to the head as their leg buckles.
I pride myself on my impact training and so far havent found anyone able to knock me out.
Having said that though I dont fight all the time, i can usually talk most people down.
In fighting games i favor karate style fighters as that is what my RL training is based on.
4 years of Goju Ryu training for the record.
In RTS i play land possession tactics, moving a moderate force forward in stages, leaving a smaller force at the last check point as a reserve.
In RPG i play DPS warriors, played a Dwarf Warrior DPS for 5 years on WoW.
I always use an NPC team member as the tank where possible.
In FPS i tend to lead most assaults and get shot to hell and back

But i am usually forcing the enemy to split the forces defending multiple approach routes as my team members tend to follow my lead and go some of the previous routes i have taken, but then im looking for another angle to charge from. Thats not to say im above sniping to thin the enemy some if i feel the assault is becoming a stale mate.
