Okay, pay attention. Capcom Arcade Stadium is the front end interface that Capcom uses to distribute ports of all their vintage games. You may already have it from their Ghosts ‘n Goblins giveaway. Arcade Stadium is free and individual games are purchased as DLC. This pretty much means that a DLC giveaway for Arcade Stadium is in fact a free game giveaway.
The game will show up in your library under C for Capcom Arcade Stadium, not under S for Smash That Car To Bits!
