The first point should rewritten as "these things". The plural form of 'this' should be used to refer to a plural object.
The third point should be rewritten as "Back in my day". That is not the correct turn of phrase.
The fourth point should be rewritten, in its entirety, as "I lived through the fifth and sixth generations of video game consoles." Please recall that the first Playstation and first Xbox were different generations of console. Additionally to say one "lives a generation" means that one lives for a specified amount of time (in this case, however long a 'generation' is), where as to "live through" something means to experience it.
The fifth point should be rewritten as "I lived through". This is the same as the fourth point.
The seventh point uses the word 'another' without drawing a comparison. The easiest amendment would be to append with the phrase "than which we currently ."
Congratulations; you're old, but you still can't pass high school English.
