There is nothing wrong with good, old fashioned debates among forum members. I don't really see any need for a ban, so you shouldn't worry. Anyway, most games are rips of other games nowadays, because there aren't many orginal ideas to come up anymore.

HALO was so great for a number of reasons. The gameplay was amazingly smooth and interactive. The graphics are bar-none, and the weapon selection was intense and original. The story line was new, but not the premise, and the multi-player option was ripped from Golden Eye, but took it to the next realm. The same can be said about Zelda, which is why these gaming titles are the most successful for their individual consoles.
