I know what you mean, I'm still glad I got Rage of the Dragons when it first came out, as otherwise I'd never have been able to afford it.
as for the multipul copies I'm talking about same game same system, for instance I have 3 copies of MGS4 one is Japanese Limited, one is us limited, and one us standered edition.
I you wanna talk same game title well I have 10 versions of symphony of the night I have 3 japanese PSX one original and 2 ps book branded, (one due to a shipping error) I have the saturn ver Both us ps ver (black lable and greatest hits) the playstation store downloaded, the 360 ver, both disc (Konami Classics) and download, and us and japanese ver of Dracula X chronicles on psp (and I have like 3 copies of DX Cronicles as well)
And don't get me started on Street Fighter, I have so many versions of most of the series its scary
