they tried. you can choose between old tank controls or modern controls. but given the grid layout of the levels and how lara has to be in just the right spot to make many jumps it can be tricky with the modern controls.
overall a decent remake and good for a couple hours of nostalgia.
That's pretty much expected for most remasters. They upscale some textures, add more resolution options, and add support for modern systems. It's like a remastered CD or movie, with the main goal (besides trying to get you to buy it again) being to release a less compressed version of the original.
Yeah people need to educate themselves on the difference between a remaster and remake.
A remaster from the music term isn't necessarily even just quality changes, but can sound or 'feel' different. But it's still based on the original 'master' recordings.
