I am playing ELEX and Assassin's Creed Origins. The DLC on Origins is actually really good compared to what I was expecting and actually felt like an extension of the game just like old expansion packs used to be. I am actually going for a 100% on AC: Origins. I am 68 hours in and probably have another 40 in the base game alone... and there are 2 more DLCs yet to come! Not much that I can really say that wouldn't be a spoiler besides what is already plastered everywhere from their advertising.
ELEX is a very European RPG. Lots of attention to detail in character development and how the societies in the game are structured/reputation systems. The game takes place a few hundred years after a comet hits a planet called Magalan and destroys the civilization that was there. The current civilization has been split into 3 factions/tribes. The groups are religious technophiles, atheist magic using technophobes, and scavengers that value freedom above everything else. There is a 4th faction that split off from the religious crowd that is trying to take over the planet by combining magic and technology. The magic in ELEX comes from a material called Elex that was created when the comet hit the planet, supposedly because of the intense heat. You play as Jax, a deserter from the 4th faction who has experienced memory loss and your goal is to get revenge on the people who betrayed you.
At the beginning of ELEX the combat is similar to dark souls, dodging out of the way, waiting for an opening, learning enemy attack patterns and style. After you join a faction and get some good gear the combat is much more gear dependant. If your armor is too weak and your weapons are too weak you will not be able to kill enemies without blowing through health items. The style of the game is open world but it is broken into acts and the landscape and enemy spawns change between acts. Even at the beginning of the game, there are very hard monsters dotted across the landscape so you have to be careful to not get into fights that you can't handle. This game oozes old-school RPG with a heavy focus on character building. I actually had to restart after about 12 hours because I was not used to needing to plan out my characters so early in the game. Also quick save and quick load are your friends since auto saving always seems to be from so far in the past that it really isn't that useful.
