Oh, I find that surprising. I’m a pretty casual game player but don’t find the controls too difficult. Maybe that’s because I take a pretty minimalist approach and don’t use most of them. A lot of the controls are optional and you can use the context menus by right-clicking the mouse instead.

From memory, because it’s been a little while since I played, this is what I commonly use, ordered by how frequently I use it:

• WASD - moving around the map
• C - crouch/sneak
• Space - shove/stomp
• Shift - run
• Esc - cancel action
• E - interact, but I believe in most cases you can use the context menus instead, like for opening doors, so I don’t use it a ton
• V - vehicle menu

I think that’s pretty much it.
