That's the thing: the game **is** unfinished, but is still fun to play as long you enjoy sandbox games. The history and missions are the weakest part of the game, if you like a mission driven game then this is not for you for sure. But it's there to give some purpose for people that like it. But if you thing is survival and building, than you may find this game enjoyable for a long time. I essentially play it twice an year, mostly on seasons, because I literally spend days planning and building and exploring - I'm playing my first planet for 3 years by now. The survival part of the game is challenging, and you will die a lot until you get your grasp on the game. But once you reach a level in which can build machines to automate the trivialities of survivability (and upgrade your suit and tools to the max levels), things get easy and you will spend your time building and exploring. The building part of the game is pretty good. Really, really good. There're some caveats (don't break a large construction in two by accident, you will never be able to merge them again without mods), and you will find yourself spending a serious amount of time finding a nice place and building your castle there. Forget about Multiplayer, this game is solo. Some Community features would be welcome to GoG users though (there're people sharing crafts on Steam Workshop, that community is quite active!) If you are a Mac or Linux user on a somewhat limited hardware, this game will need some trickery on the settings to be playable, but it will be playable even on potatos as long you have the patience to trim the settings right. Overall, it's not the best game you will find around in 2023, but it's was a pretty decent game in 2019 and it's still a enjoyable game for sandbox lovers nowadays. The game is ageing nicely, the graphics are still nice even on 2023 standards. A Ray Tracing mod would be really a game changer here. If you find it on a sale, I strongly recommend a try.
Right now, Steam is selling R-Type Final 2 Deluxe for ONE THIRD of the price announced on GOG. I urge GOG to contact NIS America in order to fix this problem, we are talking about 380R$ on GOG versus 117R$ on Steam (discounts not included). This is clearly causing prejudice to GOG.
