Sorry,I'm REALLY late,but I can explain,I passed most of the time playing Borderlands 2 with all characters,reaching max levels of all,searching for easter eggs,"interviewing" friends that play a lot this game,playing Halo 4,etc.And now,my conclusions:

The Game:

Borderlands 2 is a shoot and loot game,which consists on getting itens that drop from the enemies when you kill them.It has a great campaign,you're a Vault Hunter that must stop an evil corporation,Hyperion,to reach he Vault and control the Warrior,the multiplayer is nice,you can team-up with 4 players to play,and the enemies become stronger,helping you with XP,also,the loot gets better.Now,I'll get into details:

Campaign:

Main Quests:

The main quests are great,mixing exploration of the map,funny moments,nice characters,places full of enemies and though bosses.Sometimes its really annoying that you have to go to the other side of the map(which is huge,by the way) and give up.In my opinion,patient is one of your best options for this game.

For example,when you have to kill 5 bandit cars and you already killed 4,yesterday,I did this mission again and the 5th car took 30 minutes to appear!30 f***ing minutes!

Side Quests:

The side quests are a great way of leveling up,they give you tons of experience and,sometimes,great weapons or shields.Some side quests are also easter eggs,for example:

Easter Eggs:

One thing that Borderlands 2 mastered is easter eggs,there are tons of it,from Minecraft to Batman.I found many of them,some of them help you getting a(n) achievment/trophy.My personal favourite is the one that they made for their fan,that died with cancer D=

Overall for Campaign:9,5-It is nearly perfect,but it must improve some errors and fix some bugs.

Multiplayer:

Cooperative:

Borderlands was made for the cooperative multiplayer style,it allows 4 players to explore the map at their will,make enemies toughe,so the game is still challenging,you can grab ammo(even if not needed) to troll your friends,etc.But the coolest thing is that the loot is better,you know,the chance of finding rare itens is better,I always find at least one rare iten with other player,but most of the time someone picks it first :/

Competitive:

The problem with the competitive multiplayer is that there aren't enough modes,you can duel for fun or for an iten,nothing more,but its still funny.Another bad point is that anyone can duel with anyone,so if you accidentaly hit your friend and he hits you back,you're going to have a bad time.

Overall for Multiplayer:8,5-Great,but needs improvment.

Graphics:

The graphics are great,the cartoon style make the game perfect,it just fits.Also,the weapons and places are always almost perfect,the only problem is that it takes some time to load :/

Overall for Graphics:9,5-Reaching perfection,just make the graphics load faster and you'll have a 10

Soundtrack:

The 23 songs that are part of the soundtrack are perfect and "Short Change Hero"-The Heavy was a great choice.fits the intro perfectly and describes the game very well.

Overall for Soundtrack:10-Perfect,please do not change it.

Overall for the game:9,5

Its a great game,I would reccomend it,if you like fps's or if you're looking for a new kind of game,Borderlands 2 is definetively your choice.
