An inn for the Gold Saucer themed like the FF7 inn for the Gold Saucer.

Using the current minions, creating a new mini duel game based on the Tactics advance series (probably with shorter battle).

Making Unreal dungeon using 5-6 non-MSQ dungeon where the trash mobs are more a keen to Mask Carnival and where the players get access to some kind of lost actions. The party will need to bring the correct actions and work together to clear. Also the dungeon will have a little bit of randomness in term of which thrash spawn and which event trigger.
