For me, character progression is an important part of the game - maybe its because I'm used to Bethesda games, but I like the idea that I'm always improving. A for instance, prior to hitting the max level, I'd explore a little more and basically shoot everything in sight - I gain XP for both. Now, I just skip that, since there's no benefit.
I understand given the game mechanics that you only have a set of amount of points to add to your skill tree and only handful of points for perks, but what's the harm in loading up the skill tree, its a fun part of the game.
As for game play, I'm not really enjoying the second DLC, its quite different then the game, and first DLC. The writing is good, the game play feels forced and the depth seems a bit shallower then the Perils of Gorgon. That is, its a smaller DLC. I'm like 80% through most of the game outside of the DLCs. I'll finish up the DLC probably later today or tomorrow, depending on my free time.
Overall I've really enjoyed the Outer Worlds and it was a good decision to buy it.
