No, but accidentally I ended up with two Metroid Primes, two Super Mario Sunshines and all the four RE4 versions (that is, except the iPhone one, so it isn't all versions anymore...)

Well besides the games that I've bought several times across different platforms and whatnot like FFVI there are many games that I have two copies of because one was for me and one was for my brother or sister. We have like two Super Puzzle Fighter, two mario kart 64, two Ocarina of Time, two Animal Crossing ds, and many others.

In addition I have a couple games that I bought for just myself that I have multiple versions of

StarCraft - had the original....then bought the game + expansion battle chest...then when recently tried to get back into it and play it again found it to be incompatible with xp so went out and bought another battle chest

FFXI - Treasures of Aht Urhgan, bought the stand alone for ps2 when it came out but then had issues with getting my ps2 to read it so never installed it til much later, at which point I couldn't find it so I went out and bought another copy...I later found the original copy too -_-.. I've also bought the collection for PC that includes it and will probably get around to buying it for the 360

i got two TM2

and i want to get gta4 for ps3...

resident evil 0 - 4 i got most of the ports excepted for the pc ones and RE 5 for ps3

final fantasy 12 my friend borrowed it and never gave it back i i bought another one

SSBM i lost the disc

On the same system:

FF8 (PSX)
Phoenix Wright 3 (DS)
Starcraft (PC)
Final Fantasy Adventure (GB)
Final Fantasy Legend 2 (GB)

I bought multiple copies of other games in the past (Phoenix Wright and Wii Fit), but those were for resale.

I have also bought Metal gear solid 2 &3 and then the MGS essential version
Metroid prime 1,2 and 3 and I have Metroid collection on order
Same with Devil may cry (although I only had 3 before I bought teh collection)

There are several games that I have bought for multiple systems.
Prince of Persia sands of time trilogy for both xbox and GC (found out it was not playable on xbx360)
The bard's tale for PC and Xbox

I also bought planescape torment multiple times after losing my first 4 CD edition cause I thought the 2 disc edition did not have everything (lost both during a move .. haven't finished it till date, have to buy it again)

I bought Elder Scrolls 3: Morrowind, 5 times and then Elder Scrolls 4: Oblivion, 3 times.
