>>713876198 (OP)There are four steps up in quality.
Getting out of Temple of Trials. It's outrageously awful.
Getting out of Arroyo. The place is stale. At this time your chance to like Fallout 2 is great.
Reaching Den. First time the game has some real consistent excitement. If you don't like this place, there's a 40% chance you won't like Fallout 2. At least try to get here before being discouraged.
Reaching NR. If you don't like this place it's official, that you will never like Fallout 2. Getting here is three times as large a commitment as getting to Den.
