Twilight Sparkle's Secret Shipfic Folder is a fun and absolutely ridiculous game about shipping everypony with everypony everyone everything else. As far as I know, it is the only game where you can get points for shipping Cheerilee with Cult Leader Fluttershy, a gender-bent Gilda, and a changeling disguised as Bulk Biceps.
You should play it.
A few of us crazy people are going to play a game of TSSSF in which we will write fics for every ship we make.* And we're going to post them here. Because we have no shame.
* Well, most of them, at least. See our rules for more information.
There's a group for stories inspired by TSSSF. At least one of them seems to be someone else playing it on hardcore mode. http://www.fimfiction.net/group/203990/folder/30859/1/main
I play this game every time I go to the AFK Elixirs & Eatery in Renton. I didn't get a chance to pick it up at a con yet, so I make sure to channel my inner shipper every time I can now.
Last time, the final goal that was earned was shipping Twilight Sparkle with her brother. I'd say that's a pretty great way to end a game that's all about the ships.
