Should I use my XCOM Declassified copy

No :)

For one third of a dollar, you can't really go wrong.

Sure why not.

The Bureau is not as good as Enemy Unknown, but its not awful. It's just not as engaging as EU. I found it to be worthy of a play, it just doesnt have the replayability/depth of EU.

Saving it to trade it is always an idea, but with non-BTA games your profit margin is never going to be high, there are more than a few traders who will buy 10+ bundles and will always price it cheaper than someone who doesn't have a lot of games on offer. You can still find games from the WB Humble Bundle very cheap (a few refined or a TOD ticket).

I suggest giving it a go. If it was a BTA-level game, I might give you different advice, but its not nearly as bad as some make it out to be. Many were expecting it to be better than EU and that was a daunting task as EU is so amazing. And at the very least it has card drops, so you can get something back from trying it.

If you are at all interested in it, then yes.

For what it's worth, I don't think all that many people were looking for the game before the bundle. Also, because of the bundle the trade value of the game will now be quite low and there will be far more supply than there is demand.

It won't hurt. It isn't final slam 2 or something.

It's still a good game, worth it.

Dont make your opinion based on reviews ,the only way to know if you woid like the game is to play it.For example Mafia 2 had mostly bad reviews,but i absolutely loved it and i have played it 8 times over and over since its release.This just might be the game for you.

Use it!

i really liked the game, give it a try!

Play it, just pretend its not called Xcom. All the hate was because it wasn't Xcommy enough, but it's still a decent tacticalish FPS.
