Yes you can only have the smaller passes. But taking the GA is really convenient. You just enter every public transport without thinking about buying a ticket. I had a general abo for years and decided against renewing it when I moved to a job 3min of biking distance from home, I missed it dearly despite owning a car.

You are drunk after a late night. Some sort of public transport will bring you home. You want to do some hiking today? You just go to the nearest train station and decide at the last minute. You want to go to that music festival/concert on the other side of the country? Take the train, have a nap, chitchat or share a meal with your friend for a few hours without the stress of traffic, looking or paying for parking a car at your destination. Train is great, it allows you to move from A to B while basically being at the pub.

You might not need to access your whole country but once you realize you can you use that opportunity and realize your country is much deeper and more interesting than you thought it was.
