Some good and some bad make this game worth playing but not everything goes as planned.
For as long as I can remember I typically play the mage type character in RPG games. However, for this one, since I knew it was a lot about guns, I decided to play Salvador the tank character which I found out is not the toon most gamers pick. I thought playing a tank would mean that I would be a bit extra strong as a character but what I found was that all too often things such as shields and health regeneration were nearly worthless. Near one shot shield reduction meant that I started taking damage almost immediately. Then, it was simply amazing how many times my toon would die even with the extra bulk, powerful weapons, and gunzerking. Honestly, this guy could be as frail as a child in many situations and it most often wasn't during boss fights which, openly, were often much easier than the baddie pileups you'd encounter now and again.
As the gun toting Sal, he was extremely reliant on good weapons for at least the first half of the game I never got. The "dumb luck" random weapon system resulted in my pretty much having a constant stream of fire weapons and it was only at over half way through the main storyline did I ever find all the great weapons people raved about online. I couldn't figure out why a game would use luck as a contributing factor in the game. For me, with the WARDEN boss, I nearly just quit as my weapons were underpowered and death after stupid death with the "tank" just got annoying. I finally found a lucky spot where I could just hide and chip away at the dumb boss until he was gone. After that the over all game seemed to steady off though, again, it wasn't uncommon to be down 100% of my shields almost instantaneously more than I thought would be possible with the character I chose.
One of the things about sololing this game is that you pretty much had to put yourself a good level or two above the mission just to have a fighting chance. However, by the end of the main story I decided to just say screw it and move forward to see how I could fare against the last fight. Oddly enough, I finished the game one full level below what was required as for whatever reason they made the final boss somewhat easy. Time consuming yes but still fairly easy.
A major glitch I found on my PC run was that there were a fair amount of times where I'd be point blank shooting at an enemy and no damage would be done whatsoever. Only when I switched weapons would damage start taking effect. This is a fairly big problem in a game that requires shooting as a major piece of the game. Couple that with the fact that side missions aren't really optional in this game but nearly required makes for an extremely long game.
Bottom line is that this isn't a game you'll bust out in a weekend. It's a massive run with a million different things to do. You'll be surprised at the fun story and side missions especially when you meet up with Tiny Tina who is, by far, one of my favorite NPCs this gen. Yet, at the end of the day, as the game comes to a close you'll find yourself a little disappointed that all of the time spent results in a fairly mediocre story and conclusion.
