Have you ever bought more than one copy of the same game?

[sapient]

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)
