Taking and idea from a game and re-vamping it too make in work in your game is a great idea, but it happens to often! Game companies have become lazy, Bioware (who are my favorite company ironically) Use the same dialogue trees, combat systems, "good & evil" meter and general gameplay in most games, which is just plain lazy! But, I digress. I don't think peoples standards are too high I just don't think modern games have been meeting our expectations. I blame this on fans of mega popular franchises e.g CoD, WoW etc. If they release a new Cod for example, with minor game-play changes and short, crap single player campaign with the depth of a wall and just make the multiplayer good people will buy it! The games industry is supplying what the masses will buy, Which is a God Damn shame!
