Well, they made a four player out of it. Maybe that might be considered an improvement, in that it had the capabilities of playing like a single player wedgehead, but also to let four people play at one time. That has nothing to do, however, with the playability of the game.
If you grew up on EMs, it's just the feel of an EM game vs the feel of a SS game. They just don't play the same. For all the technology, the game played slower, to me, than the EM version. It had a "cobbled together" feel that just didn't do a thing for me. The intention and the idea was pretty cool, but the execution of it was not particularly good. EM reels click over. These just rolled. It's hard to put it into words, but if this was a meeting of old and new, then I prefer the old by itself, and the new by itself.
I'm trying to understand the mentality of buying not one, not two, but four EM games, with the complete understanding of what you were getting into, then complaining about the technology you found, and wanting to change it. If you want SS games, then that's where you should be.
I agree with Chris. This whole thread probably belongs in a restoration forum, not in an EM forum, because if you do what you intend to do here, the game won't be an EM, and as such, it won't belong here.
In my restoration experience, I've never had one game that I had to replace every single lamp socket. Some, yes. But even on one game where everything metal (stepper frames, relay frames, you name it) was rusty, most of the lamp sockets still worked fine and didn't require replacement. Unless that game was pulled from a lake, I'm having a real hard time understanding just how junky that game was. It had to be obvious. Why buy such a basket case, then complain about what you found?
