So, I finally finished Deadfire after 76 hours. I did all the possible quests and did not leave any island or dungeon aside. Some comments:
About the plot: It's not spectacular and not horrible. It seems to me an evolution of the same theme seen in PoE. While I do not find it horrible, I do not like being just a spectator in the world, watching the plot unfold around me, without any control. I wish I could do more than just follow Eothas and see him execute his plan. That's a little frustrating. I do not know how Obsidian will continue this setting after such a significant change.
About the setting: What a wonderful setting they created! Deadfire is beautiful, it works organically and day / night cycles really help create an impeccable environment. The graphic part helps a lot to set the tone of the setting and several times I caught myself just admiring the landscape and watching the characters working and behaving in the environment. The weak point for me was the "revelation" of where is Ukaizo, which was obvious from the beginning and reminded me a lot of the revelation of Chronopolis, in Chrono Cross, , even using the same idea for its concealment.
Itemization: very good, probably the best I've seen in the genre. There are problems with excessive swords and sabers and this needs to be solved, but in general, there are great, creative items. The broom and its upgrades are really hilarious.
Difficulty: the weakness of the game. We have a serious problem here and it goes through serious problems in the mechanics of the game:
1) The encounters are very similar to each other;
2) There are a few new types of enemies;
3) 1) + 2)
4) Level up is too fast;
5) Items available to the player are very powerful;
6) Items can be used to give the same bonus twice;
7) Unlimited rest;
8) Skills are usable for each encounter;
9) 7) + 8)
10) Wound is not a serious enough penalty;
11) Wound can be healed by rest and food;
12) Foods have bonus extremely overpower;
13) 7) + 11) + 12)
14) Pets give you powerful bonuses.
15) 5) + 6) + 14)
I dont know how they will solve this. Just changing encounters is not enough, its just the tip of the iceberg.
