You know, I have to agree with Lepton...IDW and IDW 2 are BOTH better games, as far as I can see. The ship movement, and weapons are better and more user friendly. I don't agree with it's physics in space, but they are definately more affable than in this game.
On the otherhand, I tried X-2 the threat...I don't know who was reviewing that game on Gamespot and other places...but that is the most unfriendly piece of HUD I've ever run across...no real tutorials of any use, not real anything...controls are jack (no offense to anyone called jack, but you know what I mean) crud, and anyways, I could go on about how bad I thought that game was.
This game...starshatter is heads and tails above that game...and is in fact, enjoyable to play...unlike X-2 which is just an exercise in tedium and how patient you must be (X-2...first response in trying to get bigger and better ships is...I have to get HOW MUCH!!!)...
