I’d like to share my thoughts on a few aspects of your situation, glancing off of what has been said so far.
Similar to what @PurpSinister said, an exclusive members game-pass with access to a lounge and pool seems like an improvement on the pool pass concept. Receptionist could be interesting but you may want to steer clear of having each “profession” as a game-pass.
Contrasting what Purp said, I still recommend attempting to balance and polish your game. You want to provide enough free content that players enjoy the game-play and feel that it’s a wholesome experience. The premium content should simply build off that, expanding on the success of features you have. You don’t want game progression cutoff or bottle-necked by requiring game-passes.
For advertising, the single piece of advice I think is most important for you to takeaway is that regardless of what you do with advertising you want to test your game and ensure its a solid experience before you start running ads. Bugs, glitches, and other technical problems can run havoc with your game’s success even with competent advertisements.
As for the actual ads, you should try to stick with Banners (728x90) and Skyscrapers (160x600), with a focus more on the former than the latter. It comes down to quantity of views, and those two variants tend to get more than Rectangles. Depending on your budget you should try to pace your advertising schedule. If your goal is to grow your group member count, you want to run ads directly for your group. If you want to bring in game revenue and get players in-game servers, you will want to run sponsors rather than ads. For both situations, I recommend spending no less than 3k robux per ad/sponsor. If possible, running consecutive daily ads/sponsors for an entire week will do wonders for establishing a consistent player-base. If you lack the budget, fund-raise, as advertisement can make a world of difference for the success of your game.
