Having fun is a must.
Everyone has different experiences, however let's not belittle the importance of Step 1. While you are correct, the significance of Step 2 CK is on the rise, it is far from superseding the importance of Step 1. Placing the term "ultra-competitive" aside, we should keep in mind that a 230 is the current average, the top of the bell curve assuming a normalized distribution. Getting a 220 could potentially knock you out of consideration for residency at many renowned medical institutions, even in specialties that are often deemed "non-competitive" (IMED, Pediatrics, Anesthesia, etc.). Therefore, the difference between a 220 and 240+ is quite substantial.
Lastly, at many schools, pre-clinical lectures/exams are a joke in comparison to what actually goes into Step 1 preparation (pathoma, FA, uworld, etc). I agree that pre-clinical preparation can make Step prep an easier experience, but it is not enough; preparation with outside materials is essential to get a good score.
