first-person game similar to Phoenix Wright

[raaat]

Is it possible to make a game with a similar gameplay as Phoenix Wright.

it's like a point and click game except it is in first-person.

It's vaguely similar to Hotel Dusk

It's totally possible, and has been done.
* In AGS, the player character always needs to be "on screen", but can be made invisible, so you can just show the location
* a useful PanoramaView module has been made that allows fluid scrolling/moving through a location, Zork Grand Inquisitor/Myst style
* all you need to do is create the proper location graphics and, possibly, script a little interface thing or two.
