[quote name='Alpha2']No of course not, why would people rant and rave over the rarity of a good game?[/QUOTE]
No, there are people who just buy it because it's hard to find. Then there are people who just rant about it because they have a copy - even if they don't play it. This helps to drive up demand for it and easier to sell. Rez is okay gameplaywise (it's a very simple shooter and that's why some people don't like it) but it's original more than anything. The visuals were stunningly beautiful and no I didn't have to use any drugs to appreciate the graphics. And I'm beginning to think Rez isn't all that hard to find - Ebay always has a steady supply - it's just people are willing to pay 80+ dollars for it.
Shin Megami Tensei - Nocturne is another game that can be easily hyped up to "rare" status. Some even posted here asking if it was rare, some ebayers put rare in the titles, I just read on gamespot in their burning questions and they said it was hard to find (in SF where I've seen copies at EB's!)
