Blacktops 2 is wayyyy!!! better than Ghost but trying to pick it up now I imagine would be difficult as you are going against players who know every nook and cranny of the game with a ton of experiance. Still in its prime it was a beautiful experience only let down by ease of quickscoping.
I really enjoyed Black ops 2 .
At the risk of sounding trolly , and I genuinely don't wish to as you make your OP with maturity and well reasoned points, you do say you are glad that you didn't buy BOPS2, which suggests that you didn't play it for a prolonged length of time (please correct me if I am off the mark)
BLOPS2 is a bit of a slow burner and, like many cods, it tends to grow on you in time until it is really good fun imvho.
