The controls don't make sense, they're completely unintuitive and aren't accurate enough for the stealth-based segments, the sound, especially that from the wii-mote is a joke, and the multiplayer is pathetic. If you bought this, you have my sympathy. If you liked it, please return to your mental hospital or maximum security prison. As for difficulty, the game itself is easy, but the control is so terrible that things are impossible. It's not a surprise, the shooter/stealth and Ubisoft games categories on the Wii are unforgivably bad. Ubisoft is doing the right thing by not putting Splinter Cell 5 on the Wii.
