Well, maybe not. I started playing again this weekend. The controls (keyboard) are way different. You have to use mouse button 2 (right click) alot.
Press and hold mouse button 2 and other keys (shift, space, E, F) for all of the combos. I find myself holding no less than 3 keys when I'm running (sprinting) from guards trying to find a hiding place.
Another note...some of the alternate objectives are downright impossible to complete. For example, the "destroy the market stands" missions. There is always a guard standing by, so you pick someone up and throw them into the stand. Guards are after you. You have to run to another stand and destroy it. By which time there are 20 guards trying to kill you. Trying to run and hide between destroying stand 1 and stand 2 is possible, but I always run out of time from the time I destroy stand 1, hide, destroy stand 2, hide, then have to run back to the dude that gave you the mission. Maybe I'm just too old.
