Brink forums isn't only full of brown nosers who agree with everything.
If the game is really working your nerves and you can't wait 2-3 weeks for the certification process on console, I'd advise you to actually trade the game in. Don't let it make you rage and get angry. It's not worth the annoyance. They dropped the ball BIG TIME and the free DLC is more of an apology than it is a thank you. I suggest if you're gonna do it pull the trigger soon because a place like Game Stop is going to catch on and start lowering the sell back price. A friend of mine who works at one said they're getting an unusual amount of returns.
You didn't read the OP, did you?
He's asking if he should trade OTHER games in to buy Brink. Not the other way around.
In THAT case, your answer would probably be "no."
Form a personal perspecitve, I'd only be uncertain about Dead Space 2, but that's because I'm a total non-fan of the other 2 games.
If you like those games, I wouldn't recommend trading them for Brink until you've played it first - rent a copy, or play it at a friend's house if you know someone who has it.
It IS a great game, but it's not for everyone. There are a few bugs (which I'm sure will be resolved in good time). There are some oddities in how the game works compared to other recent FPS titles, which make it feel unfamiliar and strange - for some people that will translate as "bad" - if you know what you're getting into, and like the idea, you're going to LOVE it.
