Sirgin's strategy may be the only solution, just having your initial purchase date.
I think the purchase date idea is a better and more feasible idea of the two.
Well I just thought of it as a compromise between having something and having too much dates making everything look like a mess.
Then you'd have to add variations like:
Amazon.com - 9 January 1997
Best Buy - 11 January 1997
Lol that's a bit rediculous in my honest opinion. Who is going to track all of that? And it won't be easy to review these submissions either.
The release date thing is pretty doable for older games (IF you can find the correct info, that is!) but not for current games. Like Tan pointed out, there's too many places you can buy games from now.
You'd end up with:
USA: regular stores - 10 January 1997
Amazon.com - 9 January 1997
Best Buy - 11 January 1997
CAN: regular stores - 15 December 1997
Canadian website - 17 December 1997
MEX: regular stores - 09 March 1998
Mexican website - 10 March 1998
I can think of 4 reasons not to do this:
1. I don't see what
value it adds over the release year field that exists now. Do you
really need to know whether a game was released in March or May 1987? Isn't it enough to know it was released in 1987?
2. Submissions would be (too) hard to review resulting in errors being accepted.
3. It would look very ugly on a game page.
4. I don't see how you could make it fit in the "my collection" page. Obviously, it would replace the "year" collumn but it would take up more place so how would that get squeezed in there?
