RPS, specifically this article: http://www.rockpapershotgun.com/2009/08/17/the-very-high-seas-ai-war-fleet-command/
I tried the game out and it was pretty clunky, and I almost didn't get it at first. I had just come away from Galactic Civilizations and I think Gratuitous Space Battles. The first one was complex, but stultifyingly dull, and I wasn't inspired by their so-called "no-DRM" policy that the lead dev and president was trumpeting to the very skies. Gratuitous Space Battles was like a super-fiddly version of Electric Football, but with none of the charm, and there was something about the developer that rubbed me the wrong way.
So here comes Chris Park with his big ideas, his "serial only" DRM and his actually interesting space battles, and I bought it a few days after reading a second article about the DRM scheme...
and more or less left it alone until it was ported to Unity and it finally started to feel like a real, finished game.
But, it was made by a developer who seemed to really care about his product and what the anal retentive I-used-to-own-my-games PC gamer demographic cared about , so it was worth the investment. Total payoff.
I don't care as much about DRM these days (all the better games eventually get released without it, so what's the rush?), but I still play AI War a few hours here and there. I just like seeing how it's evolving, responding to a few threats, dying pretty efficiently. I might even beat it one of these days.
