No it isn't the same. It isn't point-and-click, and there are several timed sequences in it. The first timed sequence, where you have to grab a frying pan, isn't that bad. But some of the later ones are very "challenging" and there's at least one where you have to sit through a long, unskippable cut scene every time you try to get past the timed sequence. I don't know if this "unskippable cut scene" problem has been fixed in current versions of the game from GOG, Steam, or other download sites.
You can use keyboard or gamepad. The camera angle will automatically switch around depending on where your character is located. Keyboard controls are camera relative and your point-of-view moves around -- so the "up" arrow can make your character go front, back, or to the side depending on where the camera happens to be at the moment with respect to your character. If George is facing to the left, the left arrow will make him go forward. If he's facing front, the down arrow will make him go forward. The biggest problem comes when the screen changes around when you're running around during a timed sequence. For example, your point-of-view can be behind George, and you're using the up arrow to run toward the back of the screen. Suddenly the camera will switch to a side view. As long as you don't let up on the up arrow, he'll continue running in the same direction. But if your hand trembles and you let up on the key for a microsecond, he'll suddenly be running in a completely different direction. There is also trouble if you have to adjust his path to go slightly more to the right or left after a screen change. The right arrow key will probably not be the one to make him veer a tad to the right. Having to experiment with what key turns him in the right direction during a timed sequence can lead to having to repeat the timed sequence multiple times.
The game is still a Broken Sword game about George and Nico and the story is OK, but I found the controls very difficult. They were unlike any other keyboard game I'd played, probably because the game was really designed for gamepad. If you have a gamepad, I'd suggest playing the game with that. If you play other keyboard-controlled games, you may find that the reflexes you start to develop playing Broken Sword 3 mess you up for playing other games (especially the ones that use character-relative controls instead of camera-relative). That reason alone is enough to use a gamepad with Broken Sword 3.
