BioShock Infinite is the marquee Day 1 Digital release on PS3 today, even allowing Plus users to download it and play a timed trial for free. Other new games on the PSN include Army of Two: The Devil's Cartel, Tiger Woods 14, and previously retail-exclusive game Tales of Graces F.
In terms of (sort of) smaller games, PS3 also sees the release of Terraria and WRC FIA World Rally Championship, a very long title that we believe refers to cars. Other assorted PS3 items of interest include Nobunaga's Ambition: Iron Triangle for PS2 Classics, and a bundle of Sega's recent fighting game re-releases for $10. And on Vita: Machinarium!
