With four controllers, play "Street Dive" in Party VS mode. On the game select screen, Street Dive is the next to last square on the second row. When the game starts, pull controllers 2 and 3 down. All three opponents will crash in about 10 seconds. Repeat until you have 200 wins. This solution assumes that you are in the top most (player 1) position. I recommend going for this after you have finished all other achievements requiring game wins.

Note: Do not completely overlap opponents or else you will have to play the sudden death game.

Assuming you have 4 controllers and don't want to play Street Dive over and over again then this method is for you.

Set up a Party Vs game and use the following playlist:
- Crate Drop
- Dodgeball
- Fruit Splash
- Reaction Round Up
- Street Dive
- Super Mudball

You have to be active playing these games as opposed to just hitting start and letting the other players crash in Street Dive; but compared to playing 6 games of Street Dive this method was saving me 30-45 seconds per playlist.

So this will only save you a few minutes probably in the long run, but if you're like me and couldn't stand the same loading screens and same winning cut-scene; not to mention work a little bit on your 26 miles achievement as well.

You could throw a couple of other quick games in that playlist like Survivor or Tram Trials, but Survivor can be a pain at times and "Trials" has a possibility for a tiebreaker if you're not careful.
