If you liked the first one the 2nd is definitely an improvement and an overall enjoyable game
The graphics; last borderlands using cell shaded engine which mean everything like cartoonist now the game using unreal engine 3.every thing in the game is design very well and work on more then 60 frame per second on ps3. The perk tree or actually 3 trees depending on which one you choose or split up uses skill points when leveling up. The badass skills gives you coins/tokens to use to increase bonuses for your character like fast shield regeneration or higher health points to gun damage and higher elementally effect chance. The only draw I would think from the badass skill tokens/coins was only having random 5 options every time you used a token. I can see that the creators of Borderlands wanted the player to evenly distribute their tokens instead of just over powering their gun damage or health.
