Well welcome to the game! It's to bad you just missed the event with bonus mpg, but I have almost made a mil mpg achievement in a couple months, there were a lot of days where I did nothing but mini cackpot, because I got burnt out, but I played triple triad, did the events that take place every 15 min.'s you get at least 2000 if you finish it, except 'where the wind blows' it's just plain out luck, mini cackpot daily if your not familiar with what to look for you try to get 1, 2, & 3 in a row to get 10k mpg, if your going to play the machines the best ones are in the hallway of minion square/chocobo square there's out on a limb & a mining one not sure of the name off hand they get you quite a bit because of being able to double down, once you get the rhythm down its pretty easy.

Once you get to the golden saucer anyways. I personally wasn't interested in that mount, especially with the price tag I mean sure if I make it to a mil & got everything I want already then I'll probably buy it. But anyhow good luck, hope this helps.
