Never been to RTX, what is there besides the Q&A panels?
I've been to RTX London 2017 and it was a dogshit experience. It was a first year event, in a country they've never hosted an event in before, I'll give them that, but there really wasn't a whole lot you could do. There where stands with people selling their goods (art, shirts, snacks, figurines, I think they were selling the RT Box at one booth even), the main stage where they hosted Q&As and live podcasts (I remember Burnie was on stage with the Sea of Thieves devs), the signing area where I got to meet Michael and Lindsay and got some stuff signed by them, a gaming area where you could play a few games (I played gang beasts there) and the panel rooms.
I had a weekend pass and I had planed out what panels I wanted to see, but to even get inside the room I would have had to que up hours before everyone else. I would get there at like 10am and the rooms where already full, so I didn't get to see any panels at all in the two days I attended, which made it feel like a collosal waste of time and money since if you just spent one day there, you could see everything, so my second day was pointless.
Apart from that, the venue security warned the organisers that they would shut down the convention if they didn't do something about the immense ques that would form. People where literally queing for the que to get into certain panels and this formed large groups of people which were deemed a fire hazard (I am not 100% sure of this info, it's been a few years)
So, in conclusion, boring convention, wouldn't go again even if I was paid. Literally the most ripped off I have ever felt in my life.
