Witcher 3. The story is insanely good, just remember: your decisions matter (but don't look anything up).

Some people say it's hard to get into it and to be fair it is a bit complicated first but you don't have to use all mechanics, and it's well worth getting into it.

It just got an official mod creator (yes, that game from... 2015? (graphics from 2022 since there was a huge graphics update) still got a new update in 2024) and the community still is strong so it'll get even better over the next years.
