User blog:GoldenApple NB/SAS4... based on...?

I just played Borderlands 2 for 9 hours a day for 4 days. And I have realized: THERE ARE SOOOOO MUCH SIMILARITIES! Sure, the aug and armor is SAS:ZA original, but damage types, and manufacturer thing is just too similar for me to get over it; Same Thermal, Chemical, Energy damage, same way the manufacturers work, and even the gameplay: level up to be stronger, and find better stuff for yourself. There's no real proog that SAS4's based on Borderlands, but just picking out a notable point.
