Couldn't agree with this more. I started climbing a month ago and I'm fully obsessed, it's like a sport designed for people who like video games. Each route is a level that needs completing and the initial progress is so fast and rewarding that you just want to come back and beat that grade that you couldn't get a week ago.
I have a 6c which I fall asleep thinking about right now, the crux seems so doable from the ground and then feels impossible when I'm there. I bought a hangboard to train finger strength so I can beat it faster, and that is definitely more akin to working out, but I see it more as grinding or overlevelling to beat that piece of shit boss you've died to 10times in a row.
Bouldering is like a phone game, each level is less than a minute long and requires a specific skill to be unlocked to beat it, over time these skills combine to allow you to beat a harder problem without you even realising you've levelled up. Top rope is like a console/pc game where levels take longer to complete and rely on managing resources and your strats.
It also helps a ton that I feel 5x healthier already and am stronger than I've been in my life. Climbing is seriously awesome.
