I'm completely paid into Season 4 with Pinball Arcade on Steam, so TAF showed up in my games list the moment it was launched. : B
As far as Pinball Arcade is concerned, they did a decent job with this conversion. My only complaint is that the skill shot is unnecessarily difficult to hit because the ball bounces off of the edges around the Thing capture spot differently than in real life. They managed to do the magnets surprisingly well too given that the magnetic effects are hit and miss across all the tables which have them...
It's one of their better conversions for sure as they've certainly done far worse, Starship Troopers being a recent example. Upon initial release there was a physics exploit with the left rank/nuke hole and an incredibly dumb lighting mistake with the upper-left flashers (which is still present). Also, despite being a six-player game you can only select up to four players. The excuse is that the engine behaves strangely when allowed to run with six, which, speaking as a programmer myself, feels like a very lazy response to that issue. : P
Another of their bad conversions is Black Hole, which has very odd physics problems all over the place, including being able to perform death saves with almost zero effort.
Still, I'd rather have the virtual stuff than not being able to play and understand these games at all. ; )
