I really agree with STALKER, easily the most immersive game/series I've ever played. I really like the visuals of Quake Live and the Scribblenauts series. Quake because it's so clean cut and there's no frills. Scribblenauts because the art is really charming.
's visuals are incredible. They could not have more perfectly represented what Chernobyl actually would be like, but it's not even so much that it's realistic. The game has that element of fantasy that I believe we all think about when we think of a post-apocalyptic Chernobyl, and the effects of radiation.
was another one I really liked. I don't think I've ever been more immersed in a game. The controls, gameplay, and the visuals all come together to make me feel as if I actually am Batman, and not just some person in control of the Batman character running around on my screen.
And one I want to mention is . The visuals by themselves are nothing special, but it's in the context of the Half Life universe, and being a remake of HL1 that makes them special. When I played Black Mesa the entire time I felt like I wasn't playing Half Life. It felt like I was playing a completely different game, but I always had a lingering sense of deja vu everywhere I went because all the models and textures were different.......but the same. The team really went the extra effort of finely crafting an alternative Black Mesa facility for you to experience as Gordon Freeman.
It was just amazing to me that a team of modders didn't just simply up-rez old game assets, or anything lazy like that as the big AAA publishers so often do when they give us "HD" collections. It's the best remake I've ever played.
