Yes, by calling a game that resembles Halo immensely a halo copy, you thereby claim that every game in existence is a halo clone. There is no middle ground, lets not try to reason at all here folks.
I generalized it on the basis that it's a futuristic armored hero game in which you engage aliens in battle, however, the storyline isn't what is heavily emphasized, just how awesome the multiplayer is. At least with Mass Effect, it had the added aspect of stat editing and choosing your path with morality.
