Namco Arcade is a weirdly stocked virtual game center for iOS

Taking a page from Turbografx-16 Gamebox’s … book … of how to sell old games … Namco Arcade offers free play of one selected title per day. You can choose one every day, or — here taking inspiration from Capcom Arcade — buy “Play Coins” to unlock additional plays. If you don’t want to deal with that nonsense, in-app purchases will let you buy the games permanently for $3.99.
