Same thing happened to us when #TWD first came out. We went down to our local arcade and saw the one person was playing it. We walked around played other games then circled back (about 30 mins later) but he was still on the machine. I noticed he had a fair bit of credit on the machine so we went to grab some food. We came back an hour later and this guy was still on the machine. We tried to be obvious that we wanted a go without impeding his game.Once I noticed he had a little cooler under the machine I knew he was going to be there for the long haul. Just wish we had the guts to politely ask if we could have had one go, but alas we didn’t. We left disappointed. Not sure if these types of players are aware of their surroundings (obviously not), but I know when I play I do look around to see if anyone else is standing around to have a go.
