Plus, you can go as hard as you want in terms of musical proficiency. You can look up chord charts, learn how to read tabs, or learn how to read sheets.
Though it should be said, guitar is tough starting out. It will make your fingertips sore and your hand cramp. It will take hours of practice to get stuff halfway decent, even things that seem simple. There's always something to improve at or learn. And no matter how much you practice you'll always hear imperfections.
It's a hell of a time commitment (and it can be a money sink) but it is very fun.
