How would you rate Expedition?
I will rate it... highly.
My biggest grip with Expedition is its combat design. Expedition is jam-packed with combat, and I see that Styg tried to came up with varied types of enemies, but most of them are annoying in some way or tedious.
Tribals are fun to fight. They have a lot of types, they overwhelm and try to fuck you in different ways. Nagas are awesome. But the rest is mostly critters and robots, and they are mostly boring. Not only that, they also have some annoying gimmicks. Sea-snakes have this heartbreaker poison and rusting acid, crabs daze you, spiders fix you in place, locusts can fuck off and die.
In my opinion, less critters would have been better. Add more varieties to robots (like, strongmen using some weapons instead of just throwing shit at you. For example, wielding strongmen dealing fire damage, cutter-strongmen with laser cutters, and such), add one more humanoid faction (like, survived deranged Lemurian mutants) and combat would have been way better.
Everything else is from good to awesome. Visuals, dialogues, lore, characters, locations, etc. Good stuff.
