I have that game. It is not bad. I have not played it in a while, but I remember enjoying it. It is nothing like the original, except the story line or basic premise. The description of what you are doing (mining for sinibombs) is the same as well as the reason you are doing it (Sinistar is comming, run, run) and the whole time you are fighting off little buggers shooting at you.
The game is 3d and is a first person flyer/shooter. It is alot like that game FreeSpace. The physics are pretty well done and the play is pretty natural. Oh yea, I forgot. You are trying to keep the little buggers from building a wormhole/stargate thing. If they finish the sinistar comes. The sinistar by the way is some kind of monster or different monsters. Not a talking dinner plate.
Good game if you see it at a garage sale but I would not spend over $10 for it. HTH
