I find the degree of RNG influence in the game overwhelming to the point where it significantly detracts from my enjoyment of the game. Don't get me wrong, I like some randomness and have been playing roguelikes for 30 years, starting with Nethack. But The Curious Expedition has randomness lurking in the wrong places:
1. Shopping in London. *puts on best attempt at fake British accent* This is London, gentlemen, the greatest and finest city in the British empire, if not in the world! It is simply preposterous to assume that basic expedition equipment - like food, firearms, and tools - would not be in adequate supply there, especially for famous ladies and gentlemen with heavy purses.
London should be the place where you can get basically anything, if you can pay the price. Some things may be in shorter supply, hence higher prices, while other things may be available at a bargain.
2. Quests that you get in London. There's exactly one, and you get to take it or leave it. If it is a quest that you are ill-equipped for (anything that requires fighting for a pacifist expedition, for example), you are just out of luck.
3. Recruiting in London. Okay, at least you get three recruits to chose from. But if you are looking for one particular type, there is no guarantee that you will ever see it.
4. Perk selection after the expedition. Okay, you get five to chose from. But it seems needlessly random, as you may not get a single perk that fits your expedition.
Places where randomness is welcome:
1. The combat system. I like it! I haven't seen anything like the dice system before.
2. Map generation. Ok, maybe it's a little bit too random, when the way to the pyramid is blocked by bottomless pits and mountains and requires a detour across most of the map. But random maps are good.
3. Shops in villages. Those are definitely not London.
4. Loot.
Another thing is that I find the inventory system odd, with its huge stacking amounts. You can stuff, what, twenty bottles of whisky in one inventory slot, but to carry one bottle, a rope, a torch and a revolver you need four slots. This punishes players for trying to prepare well. You don't usually need twenty torches during one expedition, but you'll need two or three, and they will take up one of those precious slots. Same goes for situational items like shovels - you don't know whether you will find a treasure map, so your choice is either to leave the shovels at the ship (where you probably can't backtrack to, depending on the map), or waste a whole inventory slot on one shovel.
