Vertical games that use specialized controls

[secretagentwd40]

I've been heavily leaning towards building a vertical cabinet lately and since I've got no money I've had a lot of time to think about ideas and stuff.

     I finished my first cab last year (I use the term "finished" very loosely still have got some things to finish up on that),  It is a typical jack-of-all trades cabinet -trackball spinners, tron stick, 4 players etc.  I've still got some stuff left over from that one like the 20" CRT PC monitor and while cleaning up and organizing stuff around the apartment, thought why just let some of this stuff sit around when it can be put to good (fun) use?   

I really don't have any kind of plan for the cabinet itself other than the fact that its going to have a vertical mounted monitor and I want to keep the layout of the controls very simple. 
While trying to plan what games would be played on this I went through my entire Mala list and tried to track down any vertical games which used specialized controls--anything other than a joystick---and really only found a handful of games.
   Arkanoid
   Arkanoid Revenge of Doh
   Tempest
   Tron
   Centipede
   Millipede


Does anyone see any glaring omissions?  I probably will use a U360 to avoid having a dedicated 4-way stick.  Since it looks like the bulk of this machine's library will be vertical Shmups and many classic 4 way games.   I'm thinking of keeping this simple and have maybe only having the U360 and 3-4 buttons per player.
Does this seem reasonable for amount of buttons or is there any games I'm overlooking that would need any more?

I use 3 buttons per player on my vert cab, 90% of the games don't even use that many.
A few Japanese shooters use it for special functions.

Here are a couple more vert oddballs that use strange control combo's.
Front Line -stick and push/spinner.
Ikari Warriors/Victory Road/Ikari III -rotary sticks and two buttons.

I miss playing Front Line and Ikari properly.

I don't know how special you want to go.  Besides what TOK mentioned.

American Horseshoes: trackball (same with some other bowling & golf games)
Assault: dual 4 way trigger sticks
Caliber 50: optical rotary joystick (can be played with push/pull spinner + joystick okay)
Kick: dial + 1 button (an old school classic)
Quarterback: 8-way, analog springstick, and buttons (and pre/sequels)
Toobin': five buttons only (some say you can play okay with a stick; I say you can't)

Check maws descriptions of these games.  There are other game I didn't mention; you can use ROMlister and go through the lists it outputs.  Grey out all the inputs except the one you want.

I was just kinda seeing what vertical games I would be missing on this project, by only including "the basics" (joystick & 3 pushbuttons).  I love me some Centipede and Arkanoid, but since I have both of those types of controls on my other cab I don't think I'm missing out on much by not including a trackball or spinner on this one.  That should greatly help keep my CP on this one very simple and clutter free too
