The difference does matter. Two copyrighted games can have similar mechanics. Just look at literally any pair of games in the same genre. First person shooting isn’t patented, so anybody can make an FPS game. They patented the nemesis system. Shadow of Mordor and Shadow of War are copyrighted.
You mean patent. You don’t choose to copyright things or not, all media is inherently copyrighted. This comment is technically copyrighted once I hit send. It sounds like your referring to Shadow of Mordor’s/War’s Nemesis system being patented.
Games that refuse to let you change the difficulty once you begin a game. More broadly, single player games that worry too much about preserving some sort of honor associated with doing well and make it annoying to play. Like rougue likes that have no save and quit for fear of people save scumming.
The thing I hate about parrying games is that there’s rarely ever any consistency about what you can and cannot parry and also never any way for you to learn if you’re parrying too early or too soon or what.
I saw what I imagine is a tourist attraction demonstrating that it’s “true” but you can definitely see them rotate their arm in opposite directions. They unplug a sink that that carry across the equator.
