Wikipedia's availability can cast doubt anybodies INTERNET prior knowledge claims

Looking on wiki I found that RE 1 (remake) was sold on gamecube
RE 3 was re-released on gamecube too, but didn't get high ratings (lack of bonuses other ports got)
REzero was released on gamecube
And yes RE4 was released on gamecube first then ported to ps2 Here's an excerpt:
"Special editions
The GameCube version featured two different collector's versions of the game. The first was available as a pre-order that included the game, Prologue Art book, and a t-shirt. GameStop offered another limited edition that was packaged in a tin box with an artwork book, a cel of Leon, and a soundtrack CD.[81] Australia received an exclusive collector's edition that came with the game and a bonus disc with interviews and creator's footage.[82]"
another excerpt:
"By January 2006, over 3,000,000 copies of the GameCube and PlayStation 2 versions had been shipped worldwide."
So it's not rare, but there might be store specific versions that are rare-er rare-ish, such as gamestop.
Resident Evil: Deadly Silence redirects back to RE1 so I don't know what console plays it.
Well thats it I think, if Wikipedia is to be trusted anyway. A lot of people like RE so I don't think it would be full of lies. Might not have all the information though.
