There will always being something from something else. RPG's learn from each other, and build off one another as every genre does. Artists are constantly inspired by other artists to draw things in a unique way. While I am unsure whether this is an article chiefly about a FF7 remake or how people will copy from Farmville. One thing I did glean from it, is of course, the irony of the "WoW Clone Flood". Many games were accused of ripping of WoW, only on the basis that the HUD looked somewhat similar. Even when the game play and the story were completely different. This has been a subject of contention for me, because it seemed like it was popular to call "WoW Clone" on any new MMO that had a slight similarity with WoW. Some of them may have been by design, but many others were not.
