I'd say the beauty of BB is that after playing this since 2007 you can always find something new to learn.
I play chess since way before that date, and I keep learning every day. No need for obscurity nor excesive complexity.
BB is not obscure or excessively complex. BB is challenging. It is also a very long term game. I've been playing with my current team since season 28 (my first team started on season 2 and lasted for ~20 seasons), I've climbed from div IV to div I in this meantime but I consider my team still far from ideal, I think I'll need around 5 seasons more to reach a point where I'll be able to fight for championship in 1st division level, your team is brand new, you have lots to learn, it can be painful sometimes but it's totally rewarding. You'll see, if you manage to be patient enough in a few months on every friday you'll be anxiously waiting for that training update and celebrating every pop as if it was a Real Madrid/Barcelona/whatever other team goal. Putting in other words, most of the games you find around there are like learning Portuguese if you are a Spanish speaker, it's not that hard. Think of BB as if you were learning, I don't know, German
