I know what you're saying. You're saying, "when are we going to get a cool space-based RPG on the Nintendo DS?" Okay, maybe it's just me that's saying that. At any rate, the game in question has just come out and it's called Infinite Space.
Imagine a game like "Galactrix" where you're hopping from planet to planet, but take out all of the puzzles and replace it with a combat system where you actually feel like you're in control. Where you can feint and force the other guy to make a move so you can go in for the kill.
Oh yes, you'll have space ships, each one bigger than the last. You'll be able to add components to them to make them faster and stronger and other things. But why stop at one? In Infinite Space you'll be able to build a fleet and use them to blast your way through one combat after another.
As the title implies, it's a big place and I've only explored two sectors. My fleet only consists of two little ships (okay, they're actually destroyers) and I've yet to earn the use of combat fighters. But the promise is there and I'm eager to see more.
So if you're a fan of big star fleet battles and enjoy sci-fi role playing, I think you'll get a kick out of Infinite Space. Meanwhile, I've got another sector to investigate.
