If you had an n64 and didn't have this game then you might as well have been living under a rock, I can't sympathize.
gameplay: Once you go through the whole game there is not much to come and replay but if you like the action sparsely then it dosen't hurt to run through a few levels every now and then. If you didn't conquer a floyd mission some of them were downright impossible so that adds minimal replay value and the major gripe i had was the disorganization of the missions. Which floyd mission could i or was trying to get this medallion from or whatever.
Gameplay has alot of action, shooting enemies correctly maneuvering around enemies to get the kill, by the way this game is pretty immense so don't worry if you'll be done this game quickly. The storyline in this game once you complete a cut scene it's funny it is gone forever so you feel like you're actually in real time kind of errie.
graphics: shiny typical of n64 but taken to the next level, nothing missing here. Immense levels with lots of aliens and secrets of all sorts some of them pretty amusing. I have one thing to say dont shoot the innocents those are the small un-alien like people small and tiny, other than that the game is not frustrating I got through the game. Collecting all those creatures is essential in finishing the game.
sound: All the sounds are here some of them futuristic most of them i should say.
Value: There is allot to this game if the developers had made a better multiplayer, "I've gotten a complaint" then this game would have been very superb. But this game on its own dosen't do it justice enough to say "I can do it on my own" in a sense it really needs a sequel to come ahead of all its hinderings, and maybe to reinstate an overall vibe that jet force gemini didn't get accross so well.. Either way this is one of those rare games that is neither great nor superb it is somewheres in between and concentrates more on just on going about space and killing things. This game nowadays probably looks kind of grainy to todays standards but it is still an interesting one to go through if you can adjust your eyes and forget the better graphics of today, and even do it cooperatively.
