Hyiu sums it up pretty good... I, too, stood around in arcades without a quarter (or token!) in my pocket often, wishing I could play. I wasn't exactly poor as a kid, but I didn't have a lot of money for arcades

Now that I've got the jing to run with the boys... why not have it *all*
Seriously though... I built that 4 player panel as a test, mainly, to see what I'm getting into and get a feel for the layout of the controls. My neighbors, their wives and my girlfriend + myself, we have 4+ people to play. When I originally was thinking of games I'd like to play, Gauntlet was certainly one of the "greats." But as been mentioned, Guantlet just doesn't have the same rush as it did when money was on the line... much to my Chagrin.
Like I said in my other post, I think multiple CPs are in order at this point. A dual trackball/spinner + trigger stick panel + a bare bones 4 player panel would suit just about everyone.
The 4 player panel would do double duty in this manner:
Inner sticks are Happ P360's for the 8 way games.
Outter sticks are rotary Ikari Warriors and those types of games
All 4 sticks can double duty as 8 ways for 4 player games
Then a 4 way up in the middle.
That would leave the panel uncluttered.
The "analog" panel I envision would have a trackball on the far left and far right, and two spinners down (towards player) a bit and between the two track balls, then a trigger stick would be between the two spinners. This would allow for some serious DoT action (my fav), as well as giving enough room for the crazy trackball types to really wing the ball. Would also allow for double player Marble Madness and the like.
I don't believe my panel currently is too crowded, there's not really any "squeeze" when playing. Could stuff be laid out better? Sure! No doubt about it. If I had it to do over, there's a few things I'd change.
I'm not into the "authentic" side of retro-gaming. I want it all... even if it's not authentic. I've got 2 Cabs in the works (one almost done), and I've got a Dragon's Lair I'm refurbishing... and before all is said and done, I'll probably have a 3rd Mame Cab. It's all about experimentation and learning for me. I just can't seem to get a handle on it conceptually w/o actually building it and then futzing around with it. CP's are terribly hard to build, just time consuming in the extreme. I'm not really thrilled with the wiring either! However, after wiring up the above panel, anything else is gonna be pretty easy. 150' of wiring is ridiculous!
At this point, I'm inclined to agree about leafswitches vs microswitches. I think my next sticks will be leafswitches. The click-clack of the top fire and ultimate I have on there now is annoying. The Happ P360's are pretty nice though, and a good alternative to the leafswitches if you want to roll with that kinda dough. Since cost isn't a factor for me, I want to make my panels super functional, even if it is at the cost of authenticity. The only way I'm going to get that super functionality (for me) is to try out different scenarios!
