Quoted from jimjim66:

Even if they used the original voice it would have been crap as the voice from that cartoon was terrible. The sample I showed you was cringe worthy. That is why here voice is not as grating as Beast to me.
As to the topic- Just like people said as to why it fell to where it is:
1. Came out Over-hyped
2. Worst software launch on a machine ever. Didn't even keep the right score.
3. The great software fix to make things right, was crap.
4. Night Crawlers were locking up and Stern had to create an auxiliary board to fix.
5. The Wolverine toy is not a great toy. Most people had to cut into it to try and move him as he covered too much of the Beast lane and it is so big it is impossible to not hit it.
6. With mechanical and software problems people were selling them and taking big hits on it as potential buyers knew the problems and did not have faith they would get fixed.
7. A couple of characters have crappy voice acting that can easily be compared to good voice acting on the more recent X-men Cartoons.
8. Ice ramp did not meet expectations.
The reason we have this thread as some things have changed and people do not know the original history. Many of the things that tanked it have been addressed.
1. Software has been fixed and what was once a minus, is now a plus.
2. The pin is 5k or lower and has a lot of features (back glass, pop ups, ramps), good software (deep with lots of modes), iconic theme as is 2-3k lower than pins that are only a couple of years older. ------If you buy one for less than 5k you feel like you got a steal, if the person sells it to you is an original owner, he feels like he got robbed.-------
3. People have modded the Wolverine toy with a captive ball, making that whole shot 100 times better. Borg initially had this feature in his early concepts. Too bad he changed it.
As it stands now, it is a game that is easy to flip. It won't shoot up in value, but it also won't go down anymore as it is already on the lower end for newer Sterns. Plus there seem to be a lot on the market.
