It's like you're missing the entire point of your own argument.
First you tell me that TLOU2 is NOT over the top and then you proceed to tell me how it's unrealistic for a small girl to take out a group of grown men by herself.
Do you see how that contradicts your own argument?
Ellie is taking out a group of men by herself
because It's over-the-top and unrealistic. Ellie cannot do this in TLOU1 or 2 in a realistic setting. This means the gameplay was designed for entertainment purposes and not to be taken as totally realistic.
