Carnival Phantasm 3
Yes yes yes yes yes yes.
What shows does this thing parody? I recognise Fate Stay/Night obviously and also Porkslope Turkeyhandle (I think) but what are the others?
This is parodying the games more than those adaptations that allegedly happened but never really did. The games are the good content.
Fate/Stay Night and Shingetsutan Tsukihime are the two main ones. Perhaps a sprinkling of Fate/Hollow Ataraxia later on. There's probably that fighter game.
And note this is not the only whack/parody thing coming out. Fate/Kaleid Liner is in existence and is being adapted next year. If you need something to help fill in the wait or get you in the mood, PreCure might help.
