If you're looking for a Goldeneye 64 remake, this isn't it. Goldeneye for the Wii should really be considered as a completely different game, as opposed to the N64 version. One should not compare the two although I may do so at some points. That being said, let's move on.
The story of Goldeneye isn't exactly the same as the one in the movie. This time, it's set during modern times rather than the post Cold-War. The characters look different and sound different as well. The singleplayer missions are generally the same as the ones in the N64 version but the main objective is usually different. You'll be walking through ships and running through the Russian archives all the same. For the sake of anyone considering buying the game I will not continue as I do not want to spoil the story.
Let's start off with the singleplayer gameplay. There are about fourteen missions in total, these missions are divided into the five or so main missions, so basically they're continuations. These missions are can take up to 15-20 minutes to complete depending on how you decide to complete them and what the difficulty setting is. I played through each of the missions at least three or four times, each of these times I've tried a different method of completing the level. In most of these missions you can choose whether you want to be stealthy or even run and gun, so you can pretty much go at your own pace most of the time.
During the missions there are multiple "cutscenes" which will have quick time events, there are a LOT of button mashing sequences. These are very unnecessary and annoying, I wish they were not in the game. The stealth aspect of this game was executed mediocrely, once an alarm goes off, you won't get a second chance. There are security cameras but they pose absolutely no threat to you as can simply shoot them to disable them, you'd think this would "make the guards suspicous" in a realistic sense but no. You'll get to use plenty of different weapons in the game but they all seem to have the same effect or damage, just a different rate of fire. Nonetheless, the singleplayer in Goldeneye is still pretty fun.
Now let's talk about the multiplayer gameplay, I'm sure you all want to know about this. Assuming most people who play this game, like me, don't often have friends over, so they're pretty much confined to the online multiplayer, which is absolutely nothing like the local multiplayer. So I can't say much about that but I will tell you that there are a few of your old favorite "cheats" in there, otherwise known as "modifiers", they include melee only and paintball mode as well as some others. Now I don't know if this game runs on the same engine as the recent Call of Duty(s) or it's just because it was published by Activision but the multiplayer feels TOO much like Call of Duty's, I can't really explain but just expect that if you buy this game. The multiplayer can still be fun, but it should have felt more like the old Goldeneye's or at least the local multiplayer, much less like Call of Duty. There are multiple gamemodes, they're all pretty fun, some need a certain level (or rank you might say) to unlock. As you rank up, you unlock different weapons and attachments (Whoa just like in Call of Duty!) and get this, gadgets!, which are really just "cleverly" diguised perks! Literally, all of them are like "drop a grenade before you die" and "increased hip fire accuracy" etc. So basically I felt like the multiplayer could have been a lot better, but although it's not that great, it will definitely keep you entertained for a while.
Closing Thoughts etc.
For a Wii game, Goldeneye looks great, but as great looking as it is, it's terrible optimized for the Wii as there are some big framerate drops at some points in the game. In Multiplayer the framerate is probably at about a steady 30 fps, not during action, drops quite a bit during some intense moments.
Now if you plan on buying this game, you better plan on buying a Gamecube or classic controller first because as you can imagine (or maybe even expierenced), the Wiimote is terrible for most FPSes, so keep that in mind.
