That might make sense if they were posting pictures of PS1 era Lara Croft, but they aren’t, they always use the newest examples… They would show a bigger gap in time passed if they used the dragonborn from the initial release of skyrim vs the newest remastered version.
You can’t plagiarize mechanics because you cannot copyright mechanics… And you don’t want to live in a world where you can. Imagine if the first company to make a first person shooter game copyrighted it… Or if Nintendo owned the rights to all 2d side scrolling games… Gaming would have never grown to what it is today.
Hell, even board games would have been crippled by this kind of copyright.
