is that what you feel when you were playing a game? or is that what you are going to feel when you are in the battlefield yourself?
A Simulation is the imitation of the reality which is supposed to make you feel as if you were in that situation as real as it is possible.. is it not?
So when you are in the middle of a war by yourself, it does make difference if you are on the winning side or the losing one. And i am sure all your efforts will be to carry your side to the winning side.
Conclusion: A simulation should be bearing this feeling in the name of increasing realism. Anyway everybody is complaining about one man show battles as rambo, or doom , you against the whole world. And victory is yours no matter what, yours only. Eventually, The existance of your mates in your couse is an essentiality.
