The Witcher 3

[Googolplex]

I believe you're talking about Final Fantasy 7.

Meh, Final Fantasy is ridiculous. It's like Pokémon and all that asian smooch-fantasy.

For me it felt like beta. So much stuff left out, never finished. Gothic II and III are great though

Which stuff left out? For me there's everything in what's important and I am very pleased that it's not an other Skyrim where you have the choice between thousands of possibilities.
Less is often more.

Gothic II is also great. And Gothic III is even a very good game, but this is the only part that felt like a beta when it was released. But thanks god to the fantastic community which worked over 5 years on a patch to fix almost all bugs. Now Gothic III feels like a very polished game.

But Gothic 1 is still the best, because of the deep atmosphere, story and the best german voice actors (!!!). I know that the english version is not as good like the german original, because it is not from Piranha Bytes. And for this reason you may have a loss of atmosphere impact. The original voice acting is a major thing for the experience.

Gothic is decent and not jam-full with "features" like most high-fantasy RPGs. Maybe this is what you call unfinished.
