It's perfectly possible to play with KB/M. A lot of players do. Many players who care for the flying part of the game will buy a joystick. They can be pretty cheap, but if you're not interested in flying and fighting, KB/M will do just fine.
excuse meeeee, p.... maybe you know. Anyway I even prefer KB/M over a Joystick. Hell, I do it hard on RES with ma boi the Viper, getting around 1,5 - 2 millione credits each run, without ever in real danger of death. Imo if you learn to KB/M and master it, you can do anything as good as anyone with the best/newest joystick for 1000000 million Cr or 200€.
I like to dock myself, early it was kinda hard to do, but after you did it like 1000 times you know how to speed up or slow down and which angle you need to be.
For the User who did this theard, just play as you like. But at least try to get to know everything else as well. Or at least look at it so you can master even tricky situations. If you can get a Cobra or Viper, you will do fine with exploring but get a Fuel Scoop. Cobra would be better if you like to have more Fuel/Cargo.
Do trades to get the moneys and go to explore city. You will get caught by npcs every now and than, who will try to hunter your sweet ass. But with Cobra/Viper you can outrun anything. Just go full boost and Frameshift wuuuuuush. No fear ~
Imo, your playstyle would be pretty boring, but if you like it that way nobody should stop or tell you anything else. You can love this game for what it is, or hate it. But at the end, as long as you can enjoy yourself do it.
