I often see these kinda comments and I can't wrap my head around it. borderlands 1 was decent but not addicting for me. It was stage after stage of brown, bland levels and the bazillion guns just looked to similar to each other. Sure the stats were varied but their appearance became generic. Borderlands 2's legendaries look like legendaries.
And playing any character through the first playthrough is easy. The second playthrough tests your mettle. Sal wasn't an unstoppable machine made of meat and rage in the wild life preserve on playthrough 2.
TC obviously has no clue about what he's talking about saying things like all characters play the same.
But to answer your question, new DLC just came out a few days ago. Also, some people have gotten it for Christmas. So debating on whether the game is good or bad is irrelevant because the reasons I stated are the 2 biggest reasons most people are playing this right now. That and because it's an awesome game.
I played through the game once with Salvador, then I was done. Tried the other characters for a little bit but figured out they were just weaker versions of Salvador, which I wasn't going to play much differently.
Replay value is what this game lacked, as well as different playing styles for each character. I found myself using the same kinds of guns on Sal, Axton, and Maya. Basically, everybody is good with everything, and there isn't enough variety in the skills themselves to make you feel like you are playing a completely different character.
You picked the worst character to start this game with.
This game has won multiple game of the year awards. I don't think happens to games that are "mediocre" but hey, I'm not an expert like you.
