Renowned Explorers: International Society recently came out with an expansion: The Emperor’s Challenge. This as an Asian-themed expansion, with four new crew members and a new map. The titular challenge is a new game mode, which changes the goal of the game from “gain the most renown” to “complete a series of random challenges before the timer runs out on each.”
As far as I have played it, the new content seems enjoyable. The new crew members have the sorts of abilities I like, with a mix of abilities so they probably have something you like. If you like the base game, “more of the same” is a good thing. I am apparently still somewhat burned out from having worked on 100%ing the game. (Tip: do not try to get 100% of the treasures in REIS unless you are already very close. You can invest quite a lot of time for a chance of having a treasure appear on a map, and then you have a chance to get that treasure. Many treasures * % to appear * % to acquire equals a lot of time, especially when many of them are mutually exclusive.)
The new game mode is not my cup of tea. It changes a strategic game into a more purely tactical one, and it is frustrating that you can be given challenges that are impossible to complete. Granted, that is part of the game, and you just work on the other challenges until your rival clears the ones that are impossible for your team/map/combat (nothing is ever impossible for the NPCs). It’s like a scavenger hunt mode, but not all the things to find are on the map, and the usual fog of war hides the map, and you still have the normal limits of needing to manage supplies and keep improving your team in the usual ways.
If you enjoyed REIS but thought it could use more randomness, this is your perfect DLC. If you do not like increased randomness in your gaming, this is not for you.
