I prefer the Premium by far - BUT you have to fix the left orbit issue, that is the one thing that will ruin the flow of the game. Once that is done, you're golden. The upper playfield rocks IMO, and you have a whole additional Multiball mode in Castle Multiball.

My thoughts regarding "Flow" on GOT Pro vs Premium:

The left orbit issue *IS* the flow killer on the Premium - NOT the upper playfield
- This is totally fixable - although it's not the easiest fix, so you find a lot of games with the issue
- The only other difference in Flow (Pro/Pre) is the left ramp mini-PF pass-thru, which is very minor

Here is why the Upper Playfield doesn't hurt the flow at all IMO:
-----------------------------------------------------------------------
1) It's a pass through upper playfield - if you don't flip it doesn't make much of a difference at all
2) The Right Ramp is *barely* used in the game (especially on a Pro) LOL
-- It's the Stark Shot - so you have to shoot it 3 times to light Stark - a couple more times for WIC
-- Once Stark mode is started, you can shoot either Ramp -> and the left is MUCH safer/easier
3) On a Pro almost anytime the right ramp is used, the left ramp is a safer/easier alternative - so why even shoot it???
4) The shot itself is exactly the same - the only difference is it takes an extra second (if no flips) to get to the left flipper
*update* - the drop target in front of the right ramp on the Premium does make the shot harder (more hits and risk)
--- I like the extra challenge/risk of the drop but YMMV

Premium Pros:
----------------
1) On a Premium the Right Ramp has a more important role -> to access the mini-playfield
-- you decide if you want to focus on the mini-playfield features or not
2) The Mini-Playfield adds another level of play/strategy to most other modes and multiballs
-- A key factor being you can make progress, increase values, etc. safely - draining is not a risk from the upper playfield
3) Castle Multiball is a really cool MB -> Stern just needs to increase the scoring to make it more valuable
4) IMO it's a great Mini-Playfield with 2 full size flippers and 6 different shots

*IF* you like mini-playfields, this is one of the best - hopefully Stern gives GOT an update to utilize it even more!

Exactly the same for Premium! - Once you fix the orbit

Midnight Madness is automatically started if the internal clock strikes midnight while you are playing.

You did nothing to trigger it - other than playing at the right time of day.

The issue is a diverter on the orbit to the upper playfield VUK. When not diverting, it disrupts the ball on a left orbit shot and the ball will usually not make a full orbit. It will usually go into the jets, and sometimes come back down the left orbit.

All Premium/LE games seem to have the issue from the factory. Stern provided a software "fix" by disabling the left orbit versus a hardware fix to provide a smooth left orbit. There are multiple things that can be done, but the best typical fix is to take the orbit diverter out and increase the bracket hole size, and replace the bracket in a specific manner.

This issue is so prevalent, IMO it's the real reason why most people think the Pro is so much faster / flow. After playing a Premium/LE with a great working left orbit, the Premium is practically at the same level of flow / speed, with more "cool stuff" going on in the game. GOT is a game where you need to trap up periodically or the speed will drain you in short order anyway (Premium or Pro).

Important note for any GOT Premium/LE owners:

To fix the Orbit issue, you must do 2 things:
- apply the bracket mounting holes fix
- AND re-enable left orbits in the menu (the most recent software disables them by default!)

I actually prefer having the "Tunnels" on the Premium/LE. I find the Pro too barren, and not as interesting to shoot. I always preferred train sets and race car tracks with bridges and tunnels too. I think it's cool when I nail a left orbit and the ball goes into the tunnel, and comes flying around on the right orbit. It doesn't catch me by surprise or make it too difficult, it's just cooler. I've been thinking of changing my lighting to make the left tunnel shot darker to enhance the effect!
