Which happens with most engines. UE5 is an update version of UE4 and so on.

Im having fun, but i enjoyed FO4 and TESV. Vanguard quest was quite good, main quest a bit meh, but im getting what i wanted.

Gothic 1 and 2. Weird control scheme you have to get used to, but very good games world building snd character wise. Can be quite challenging with the combat, but quest allow tons of ways to solve problems.
