michel123456, do you know that 3D FPP game players won't touch it? We use WSAD!
There is also couple other issues for game players.. left ctrl must be the most left-bottom key to be easily accessible (by the smallest finger)..
It's "crouch" functionality. While crouching player has to be able to press WSAD keys at the same time.
(on your "conventional keyboard" it's also in wrong place for gamers. It must be some laptop keyboard?)
Left-alt and right-alt keys are widely used to enter regional characters not existing in English charset.
They must be in such places so using just one hand can hold alt and be able to pick up other key at the same time.
E key + alt key in your layout is very hard to get (especially for women and children).
Also N key + alt might be problematic.
