I want another shooter, I can't decide between Destiny (not taken King, but the ORIGINAL Destiny) OR Killzone Shadow Fall... I ENJOYED KIllzone Mercenary and I heard Shadow Fall is just as fun as Mercenary.... but I also want Destiny too because it's popular. What should I choose?    

If you're not planning on getting any of the add ons, definitely Killzone. Destiny is extremely unfulfilling as a standalone package.

I agree, got bored of the standalone destiny very, very quick but took me a good while to go off killzone, not played it in a while though so not sure what the community is like.

Destiny (with all DLCs) is super cheap now, so just go with that.

Niether there both unfurfilling games. Get Wolfenstien

Why would you get destiny without the taken king??? The legendary edition comes with the base game with all expansions included. For reference, I waited for a discount and got it for $30 (includes basically everything, along with a month of ps plus). I would suggest you do the same.

If you truly don't want destiny with all the dlc (for some strang reason), then I guess I'd go with killzone shadowfall

Destiny is kind of dead right now, plus vanilla Destiny is very very parse on content. A lot of stuff was locked behind TTK so I'll have to say get Killzone for sure.

Killzone probably as Destiny 1.0 is pointless. You have to get all DLC and the Taken King if you're looking at Destiny.

Mercenary is more fun than Shadow Fall, BUT, seeing as how I've heard the base Destiny game has been ruined without Taken King, I'd go with Shadow Fall. It's still fun, but not as good as the PS3 games or Mercenary.

I voted for Destiny but you have to get it with the complete Taken King package.
