I really enjoy the new Casino area. Otis being part of the BIPED OUTREACH PROGRAM made me feel more welcome. I liked the storylines and even the little things like Eveline Rastin's shop standing out when going down the hall by having drapes. It adds to the personality of the character. I think the recent changes to the Mantid game giving cashfall tickets for close calls is great. It may even be too much. But with it giving better xp and cashfall tickets, I haven't played the match-3 game at all since. It wasn't useful to play that game and have my inventory fill up with random items of questionable use. I saw in the patch notes some things were changed, so I need to try it out again.
Things I would suggest
1) If a mantid table has 10 players and you die, it should hold your spot to be able to play again like the instructions suggest. The other day I unlocked 2 table buffs and whenever I died, it'd take a minute or two of clicking to get back in the game. Maybe table buff unlockers always have access?
2) When a new arena match is set up and the announcer says he is taking bets, it'd be nice if he told us who will be fighting.
3) I'm not 100% on this, but I don't think I could hear the announcer in the high roller room. Can the announcer be made to be heard in a larger radius? Only other thought I had (and it'd probably be too much work to bother with) is to have the high roller room above the arena. Maybe with a section of transparent floor. That way people in the high roller room could watch the fight below, and the people who don't have high roller access can look up, feel envious, and wonder what's in there.
