No problem, thanks for accepting. Good for you! It took me a really long time to decide on what I probably want to do. I had been through every idea in the book haha. Vet, astronaut, marine biologist, etc... Yes, the medical field is huge, thank goodness for that.
Yeah, you Battle against other players who do the same, but it's kinda rare to find people on the Forums who play them on WiFi, so for it Competetive Battlers tend to use Online Battle Simulators for them
Well, the amount of money you can get if you do it perfectly in the turns is almost double of what you pay.
Except the Sushi High Roller, where you get no money at all because you pay just as much as you earn.
Regarding the Thread o yours, in the Restaurants it's kinda like the Maid Battle in Platinum, in that if you follow the correct amount of Turns, you get Items, but these sell far a massive amount of money.
