Definitive edition Black Mesa is definitely prettier. It doesn't really show in Earth levels, but it shows heavily in Xen levels. It now feels much more moody, lush, and beautiful than it was - and it WAS beautiful before.
What caught my eye are godrays. I remember how Fallout 4 was marketing its godrays and other foggy stuff. And then you couldn't see it, because the game was a broken mess. This is not the case with Black Mesa. Godrays and fog and lighting effects are perfectly done and execute marvelously on my not-so-much powerful machine.
10/10.

Open World, Sandbox, kinda Post Apocalypse. If you like Mount and Blade - you will like this too. If you thought MnB was easy - you will LOVE this game.

Despite this game being Early Access one it already feels like a well fleshed out project. Don't let that "simple" artstyle deceive you.
If you like to build stuff - you will like it. If you like realism in your games - you will like it. If you like creating complex systems and tinkering with them - you will love this game.
One of the best things to me is native ability to configure your gameplay experience. You can switch off hunger, for instance, if you feel it bugs you and build your station in peace. You can increase the yield of ore processing so you don't have to mine a lot. And mods, they are natively supported too.
User support and bug-reporting/fixing is great. Almost each day something is fixed, added or remade to provide the best experience. Developers are easy to contact.

Buy it if you haven't done that yet.
