Target Earth music is great. I agree with Geise (sorry for capitalizing your name) it's better than Ranger X's music. The Master System can't do omni-directional parallax scrolling. I can't imagine someone not being able to get past the first stage. I got way far in the game when I bought it without any game genies or save states. I may have even beaten it, I'd have to check my notes if I could only find them (yes I kept track of that stuf). Cybernator may indeed be the better game, but Target Earth is still awesome.
Parallax scrolling does not good graphics make. Sure, the SMS couldn't handle that, but the game's graphics are pretty simple otherwise. I'd rather see detailed graphics that take advantage of the Genesis' color pallet, or at least look artistically inspired than graphical gimmicks (even though I do love me some good parallax scrolling.) I do
like Target Earth, I just feel it's a huge letdown when you compare it not only Cybernator, but other Genesis games. As far as the music goes, there are some tracks I like (particularly the ending theme) but the compositions are soured for me by the somewhat obnoxious tones they used. Ranger X may not have the greatest soundtrack, but at least it's unobtrusive & fitting for the game. I especially like the jungle stage music.
It seems like I'm hating on it a lot, but despite all I said, I do enjoy Target Earth even if for no other reason it's an Assault Suits game. I probably just need to give it a better chance; that's what happened with Ranger X. I've had that game since I began collecting for the Genesis & I only just now got around to getting anywhere with it & truly appreciating it.
