I bought Fortnite when it was 50% off a couple of months ago. Since October, I have put over 150 hours into this game, and I am only level 45. The game is getting repetitive at this level, but I can’t stop playing it. This game is well worth the money I spent on it ($30 for 150 hours). It is still not officially released, I don’t know how I feel about that, and there are issues with the game (it currently produces a crash report every time I quit the game). They have a consistent release cadence and events every couple of months that change your goals. I wouldn’t buy a higher-level founder pack because you can earn loot lamas quickly, especially with the event lamas.
I made a Fortnite Logitech G13 profile because one didn’t exist. The profile works well in Save the World mode, I haven’t tried Battle Royale, but I assume the keys are the same. For Battle Royale, you might want to change up the joystick to make it quicker to switch weapons and drop items (at least, that seems critical based on Youtube videos I have watched). If I ever play Battle Royale, I will add an M2 layout if the layout needs to be different. Below is a screenshot of the keyboard layout I created.
