Erm... I've found it to be the exact opposite. A complex menu hierarchy gets unwieldy when there are a plethora of programs installed.
I use games folder in start menu as primary and then subfolders for each genre of gaming, no problem for me. I like to browse the menu so I can see what game I feel like playing today.
By your opinion you should dump Windows and use Linux cli exclusively. I`m a visual person and like visual feedback so don`t really care which method is .5 sec quicker.
