Who doesn't love it when golden oldies get a re-release over the PlayStation Network or Virtual Console? Game collector, that's who. MTV Multiplayer examined collectible game values and saw many nosediving after getting a reboot on the current generation.
Some highlights or lowlights - really, you should go see the whole thing - Marvel vs. Capcom 2 bottomed out after releasing to Xbox Live Arcade and PSN this year. After reaching highs of $109.99 (PlayStation 2) and $91.99 (Xbox), they slumped to $43 and $30 respectively after the title went out online. Ouch.
The games get a dead-cat bounce but prospects for a recovery beyond that aren't good, if Castlevania is any indication. Castlevania: Symphony of the Night in its PSOne form hit $50.75 in December 2006. The next year, the game was released on XBLA and PSN, dropping the hard copy value to $19.99. It's recovered slightly to $27.12, but that's just a little over half its pre-re-release (say that three times fast) high.
MTV Multiplayer did its analysis according to VideoGamePriceCharts.com. Really, though, take a look for yourself. They covered much more than those two titles above, and offer tips for the safest investments unlikely to be undercut by re-releases.
