I bought it for that price and I've mostly played it alone, it's still worth it

You should definitely buy this. I don't think the game got enough recognition. It was my favorite game last year. It's definitely more fun playing co-op, though. I played through the whole game with my wife.

Borderlands will ruin friendships if you play with the wrong people, so much looting. Single player was still good for me, but I was never really motivated to buy the expansions. I would recommend it though

Buy it. I played multiple playthroughs by myself and it was still a blast. It is just a plain fun game.

I thought it was boring and overrated and you should spend that money on something else and the only time I enjoyed it was with other people.

It's totally worth it. Get it.

Buy

Get it. I played with friends a decent amount but put way more in alone. It's awesome.

Get it, it's so worth the full 60, so for 26 it's a steal!

I don't know if I would have blew $60 on it either.  There are actually very few games that I would really say have been worth $60 to me.  But for that $34 bucks.  That is a good deal.  I have been playing through my Steam version that I got for $10.49 about a month ago and have been really enjoying myself.  
 
Just make sure you are into the whole "looting" thing.  That is a huge part of this game, and I can imagine that if you are not a huge fan of that, or just don't care much, this game might not be as fun.  But personally, it is funny, full of personality and generally just an interesting and different experience.  I am really happy they decide to go for the cartoon-ish look, gives the game some extra distinction and allows it to be more fantasy based and less reality oriented or worried about explaining how things happened because it is almost assumed that this is a cartoon so anything is possible mentality.

I actually thought the game was very overrated.  If you want loot hunting / dungeon crawler / exp. grinding, there are far better games out there.
That's not to say I wouldn't buy it..  But at this stage, I'd hold off.  Chances are they'll release a GoTY version with all the expansions shortly.

I punched my brother in the face during a Borderlands session. Don't play it with friends. 
But you should buy it for that price, too bad you missed the DLC sale it made some of those packs more appealing. 

buy it.

Just do what I did: bought the game, started convincing others to buy it too.  

If you buy it there'll be trouble...if you go there will be double.
