PS3

Exclusive - 6
Multiplat - 14

Xbox 360

Exclusive - 2
Multiplat - 9

I've always preferred multiplats, I think most exclusives are overhyped. I would go into handhelds, the PC and Wii but it would take ages to go around the house counting.

PS3
Exclusive: 25
Multiplat: 20

PS Vita
Exclusive: 5
Multiplat: 3

I didn't think about that one, so I guess I need to edit mine.

What does partially exclusive mean? HD remakes?

Only exclusives on the PS3 and mostly multi platform on the 360 but still have most of the major exclusives.

PS3:
- 20 exclusives.
- 4 multi-plat.

Wii:
- 9 exclusives.
- 1 multi-plat.

Vita:
- 3 exclusives.

I'm too lazy to go and count through my games right now. I know all 5 of my Wii games are exclusive, though. My PS3 collection is probably encroaching 150 games now, so I will go through them later.

PS3
Exclusive - Probably around 40-50.
Multi - Probably around 80-90

More like my wife is rich. lol

Now, that's what's up!  People love to go head to head with these "List wars" but how many actually buy the exclusives they champion?  I put my money where my mouth is.  I know what you said in the OP, Kylie but I can't be arsed to see which games are on the PC since I don't own that platform.  What I'm going to do is name the games I own for the big four (Wii, Wii U, 360, and PS3) that aren't available on other home consoles.  Keep in mind that if we were counting digital downloads, EVERY console would look much, much better.

Wii U

• New Super Mario Bros. U

• And for the record, I cashed in my Gamestop rewards points and got Ninja Gaiden 3 for the Wii U, today.  It was HARD to pick up that game for the Wii U for $59 when I could have gotten the collectors edition (a HUGE box on the shelf--I don't even know what was in it!) for just $39.  Same thing with Arkham City.  I wanted to buy it but I already own it for the 360 and even if I didn't, it was much cheaper.  C'mon, Nintendo.  I loves the third person Action/Adventure games.  Hurry up and bring it!

And for the record, every title I named is right in front of me.  I can put my hands on them RIGHT NOW.  The only titles I've traded that would fit this list are Killzone 3 and Velvet Assassin.  Feel free to remove titles based on your definition of exclusive.

I have a shit ton of games that were exclusive for a long time, too.  Will add them later, I guess.
