Pro-G writes: "Portal works so well it's unreal. The game subtlety introduces you to its mechanics with a learning curve that's just right. An important thing to mention about Portal is that despite it being a single-player puzzler, it works wonderfully well with a friend or two watching, helping you work your way through to the main game's climactic end."
"The simple ideas are often the best, and Portal, quite simply, is one of the best ideas for a game we've ever seen. It's fantastically realised, brilliantly executed, and had me wrapped around its computerised finger for two-and-a-half unforgettable hours. Don't let it become The Orange Box's forgotten son - this is gaming in its purest form."
A gameplay demo of the cancelled Portal prequel F-Stop using recreated assets features no portals, and a unique camera that duplicates items.
From GamesReviews:"Portal with RTX is a fresh look for the 2007 classic. But it's not easy to run, and the results may not impress everybody."
Portal RTX may look like a quant remaster, but that couldn't be further from the truth. It's one of the most demanding games available today.
And in a bad way! This is not where gaming should be going. We should focus more on better physics, AI, more meaningful writing, substance in storytelling and overall art over reflections and lighting effects. But hey, you've got billion dollar companies trying to sell you stuff, so I guess you have to make a whole ecosystem around ray tracing because people make a living out of it on youtube. Talk about losing touch with reality and taking eye off the ball. Advancing gaming as a whole my ass!
