Here is an interesting game on steam which got everything to be really good but got mixed reviews: Citadel: Forged With Fire.
The game is an online sandbox RPG, with magic, crafting, and exploration. It is still in development, so technically early access but it can really become a perfect sandbox in a medieval/fantasy world. The map is 36 square kilometers, and because it is online you will meet other players on it and can create alliance. Apparently, some players also created amazing custom castles and fortress strongholds
The good news is that the game is for free this weekend on steam which is a great opportunity to test it!
Citadel will launch its full game worldwide next Friday, November 1, on Xbox One, PlayStation 4 and Steam.
Blue Isle Studios plans an extensive roadmap of free content updates for Citadel, announcing its first DLC is slated to launch in early 2020. The initial milestone delivery will feature narrative-driven quests, the most widely requested feature from the community. Players can expect a steady cadence of post-launch content to come early next year.
