Quoted from chuckwurt:

Have boxes and boxes of pens at the check in desk. They seemed to be scarce.
Have free bottled water for all the competitors.
Continue to improve the stream (make sure there’s no chance of glare on the games that are on or off stream)
That’s really all I can think of. This bad boy is a well oiled machine already.

Quoted from zacaj:

More chairs and tables. I don't get why there aren't chairs in every row; everyone needs to sit. Those couches were amazing the one round I was on the stage.
Water coolers in each row would be nice.
Better PA system for announcements. It's always so hard to make out.

Quoted from AUKraut:

if we can't have free water for tourney players then at least have the concession open during the tournament. Saturday playoffs started at 0930, yet concession wasn't open until 1100.....

Quoted from NIQ:

Whether a game is malfunctioning or a player needs a ruling, I want to say we answer anywhere from 10-40 tech lights a round. The first 2 rounds are the worst as the games haven’t had heavy play in a year. As well as we swap out an average of 3-4 games per round. The chairs would just get in the way.

Quoted from MrBally:

At the Cobo expo center in downtown Detroit, Max from Roumell Catering (The original food service contractor there) would go around with an open end wrench shutting off every water fountain in the place during the auto show to boost beverage sales.

Quoted from Nhpolarbear:

With all the money invested in broadcast technology it would be nice to see the coverage expanded.
A mobile rig that could be moved around during early rounds focusing on random groups would be a great add on but not a necessity. I realize it’s a big area to cover with a wireless signal. Perhaps letting some independent broadcasters participate in early rounds might be a solution?
I have seen other broadcasts with two machines on screen at the same time to double the coverage. This would be an added bonus as the tournament winds down. You could follow two, four player games at the same time.
The one big positive is the commentators were knowledgeable and scheduled to appear. Careful thought and planning could be seen. That tends to be the biggest downfall of other tournament coverage.

Quoted from Whysnow:

Step 1: Charge more money to enter (lots of demand and pretty sure we will all happily pay it, within reason)
Step 2: Use that money (NOT for more prizes) but for improvements
This thing is a GREAT event so any comments are just feedback out of love and to make it even better.
More pens. turn that 500+ into 1000+ Guessing a sponsor would be happy to do this? Hell, I would be happy to sponsor this for next year
Better audio/viewing experience. I covered this in the main thread, but the current audio is very bad. I get that the desire is to broadcast the main event to the actual public in attendance, but there must be a better way? Maybe TVs with their own audio on for every 5 rows of chairs. Then groups can better watch and hear the stream. Bonus is not distracting others that are still competing.
Need to fix the issue of bumping people out of a division via restricting others and a hard 200 person limit to each division. Honestly, I am fine with lopsided divisions. If 200 qualify for A and then you have to bump up 20, then it becomes 220. Does not seem right to push others out. The hard reality is that with the current system you could have A restricted players take up about 120/200 spots (top 100 IFPA, plus previous restrictions for past years performances) in A without winning a single point on Thursday. Alternative option is, miss your restriction cut off and you are done after Thursday. I dont particularly like this one, but it is still better then bumping others that earned the spot.
Improve the WIPT to allow for more players (apparently more than 50% waitlist full) and a full playoff. Time constraints stinks so pay for an extra hour or whatever it takes to allow this to expand. Maybe start it earlier?
Figure out how to accommodate more people into Pinburgh. With 1000 and insta sell out, it is needed. Not sure how the heck that happens???

Quoted from Coolpinballdino:

More chairs around each bank and I thought it was crazy that during the first two rounds of A they had no stream running or link. I also hope they change for next year during A finals as a player hearing them in the commentary booth blasting in your ear was very annoying and distracting. Another thing I think would be nice to see is more pinball supplies for sale in the vendor sections compared to some of the more useless stuff.

Quoted from PrinceOfPinside:

For the first two days, the two projector screens on both sides of the stage were either not used or displaying static images/slideshows.
Using them to display metrics about the tournament would be a better utilization of them - e.g. a list of the top X players with the best W/L ratios (overall on day 1, per division on day 2)
Other than that, the event was very well run.

Quoted from nikpinball:

A possible fun suggestion would be to have a couple of banks streaming live full time, throughout the tournament. Players of any caliber would get a shot at some limelight since the banks are randomized, a chance to crush it or not crush it but to be able to say they played live in front of an audience at a world championship event.

Quoted from wmanningiv:

Those bathrooms were a DISASTER! Obviously a convention center issue and not a Replay issue, but their condition all weekend was inexcusable.

Quoted from chuckwurt:

This is a very important change and an easy one to implement.
Top 200 make A. Then add the restricted people to that. Do the same for B C and D. Then the remaining players are in E.

Quoted from chuckwurt:

I think now that it’s going all the way down to E division it wouldn’t have as many complaints. But just a thought. It’s much more important that the players that earned spots, get them imo.
