The Good:
KFG Wednesday gaming at the Ram - always good fun; ditto their pub crawl Tuesday evening
Dice Cup (drinking game) at the Ram - also good fun, what I remember of it :)
The Ram in general - yes they might run out of some things but given the crush it's forgivable, and this year (unlike some past years) all the staff I met did an awesome job
Cosplay Deviants - to counterbalance some votes above: ye gods, some people are prudish
Tower of Gygax - first time I've made it over to this, and now it's on my don't-miss list
Meeting some fine interesting people who I hope I someday see again
The bigger dealers' hall - more room for more dealers
Homewood Suites - over my 6 GenCons (all in Indy) I've now stayed in 5 different hotels, and this one was the best
20-Sided Rye - way better than last year's brew
The Bad:
(self-inflicted) Thursday, after one too many rounds of Dice Cup on Wednesday night
(personal) The Auction Store - I usually come out of there with all kinds of stuff, this year nearly nothing as they just didn't have what I was after
Is there any chance all the Magic card resellers/traders could be bunched together in the dealers' hall a la author's avenue? Ditto all the dice vendors.
Dealers' hall layout - too many aisles were broken up by having a large vendor booth in the way; this makes it hard to check everything out in any semblance of order by going up one aisle and down the next
No Killer Breakfast
I was really looking forward to the video games in the corridor to Lucas Oil but was greatly underwhelmed by what was there
The GenCon Dance - more of a "meh": for some reason I just couldn't get into it this year, though it seemed I was greatly in the minority as from what I could tell a good time was otherwise being had by nearly all present
The Ugly:
Tilted Kilt - pricey I can live with; pricey with poor service I can live without
People who insist on wearing huge backpacks on their backs in tight quarters such as the dealers' hall or while boarding an airplane (hint: if you reverse it and wear it on your front you can see who or what you're clobbering with it)
No official WotC presence (but if you think this is ugly, just wait and see what happens if they don't show up next year for the 50th - whether they like it or not, WotC are the custodians of much of the history GenCon 50 will be celebrating)
The flight to Indy (arrived 3.5 hours late) and the flight home (arrived 4.5 hours late); in both cases getting in late enough at night that the only option to get to town was a cab* as everything else had long since stopped running. First time I've flown to GenCon, and probably the last.
* - no, Uber is not an option
