Nintendo gets criticized a lot for making the same games over and over. That's not really true; they make very different games that use the same characters and tones over and over. That's the Nintendo double-tap - their games look and feel like something we've seen a thousand times while throwing out the opportunity to build on what came before.That's the biggest problem with Steel Diver: Sub Wars, and my greatest fear for Nintendo's future forays into free-to-play.Let's back up. I'm getting ahead of myself by calling it "free-to-play." Actually, that may have been Nintendo. Or maybe, rather than jumping the gun, they're simply behind the curve again.
